Sam Amick of USA Today covers topics from around the league in his A-to-Z column, and with next week's trade deadline looming, it's no surprise the latest edition is full of intriguing tidbits. The Nets and Grizzlies figure prominently, as well as Josh Smith. We'll round it all up here:

• The Nets' efforts to land Smith aren't as aggressive as recent rumors make it seem, but Amick wonders just how much owner Mikhail Prokhorov is willing to spend. Despite the billionaire's deep pockets, the team's front office is under instructions not to add more costly contracts unless they significantly improve the team's title hopes.
• Brooklyn was interested in Rudy Gay before he went to the Raptors, but the Grizzlies rejected their offer because it included Kris Humphries.
• The Grizzlies, meanwhile, were "thrilled" to acquire Ed Davis. Amick refers to him as a fourth-year player, but he's only in his third season. Nonetheless, Davis will be up for an extension this summer, and Amick notes that Memphis views him as a part of the team's future.
• Smith's representatives have reached out to other teams and given them indication that he's unlikely to re-sign with the Hawks this summer, but many front offices don't share Smith's view that he's a maximum-salary player. One such team appears to be the Mavs, who have abandoned discussions with Atlanta about trading for Smith.
• While noting the Bucks' future salary flexibility, Amick speculates that Ekpe Udoh could draw attention from other clubs as "the sort of young, defensive-minded talent on a rookie contract that teams crave."
• Raptors GM Bryan Colangelo is still anxious to trade Andrea Bargnani, but there hasn't been a lot of interest from other teams.

Reaction has been pouring in since the Grizzlies, Raptors and Pistons struck a deal that's headlined by Rudy Gay going to Toronto. Couper Moorhead of Heat.com thinks the trade is a win for the Grizzlies, who pulled off the rare trifecta of shedding salary while improving short-term and long-term (Twitter link). Ken Berger of CBSSports.com sees it as a step back for Memphis, and another reminder of the harsh reality of the new CBA for small and mid-size markets. Here's more of what we're hearing:

• Raptors GM Bryan Colangelo said to expect more deals from the Raptors before the deadline, notes Steve Buffery of the Toronto Sun via Twitter.
• Vince Ellis of the Detroit Free-Press, after discussions with those around the Pistons, wouldn't rule out the idea of the team keeping Jose Calderon around (Twitter link). I assume he means the team would try to re-sign him this summer, rather than merely pass up opportunities to flip him to another team before the trade deadline. 

Earlier updates:

• Berger, in the same piece, says it would behoove the Pistons to trade some of the $26.5MM in expiring contracts they have as a result of the deal.
• As Chad Ford of ESPN.com notes via Twitter, the trade nets the Grizzlies an additional three wins according to trade machine metrics that were created by Memphis executive and former ESPN.com scribe John Hollinger.
• Not all of Hollinger's prior work portends the future, as Ford also points out, since Hollinger had new Grizzlies big man Ed Davis, the 13th pick in 2010, rated as the 54th-best prospect that year (Twitter link). 
• The Grizzlies and Raptors were calling many other teams in their efforts to faciliate the trade, and the momentum toward the deal picked up steam this afternoon, recounts Vincent Goodwill of the Detroit News (Twitter link).
• The Pistons' cap space for this summer increases from $25MM to $33MM as a result of the trade, as Keith Langlois of Pistons.com notes via Twitter. Langlois speculates that the majority of that space will be used in trades rather than to sign free agents (Twitter link).
• The Pistons, who tried to acquire Jose Calderon around the time of the 2011 draft, have been high on Calderon for a while, Langlois notes. (Twitter links). 
• Grantland's Zach Lowe thinks Andrea Bargnani and Linas Kleiza could be the next Raptors on their way out of Toronto (Twitter link).
• Ryan Wolstat of the Toronto Sun, who also believes Bargnani is on his way out, hears that the Grizzlies tried to send Darrell Arthur to the Raptors as part of the deal, but Toronto opted instead for Haddadi, whom they will reportedly waive (All Twitter links).

8:23pm: The Raptors sent out a press release confirming the deal for all three teams. The second-rounder headed to the Grizzlies is Toronto's own 2013 pick, and Memphis is receiving cash from the Raptors as part of the deal, the statement notes. 

8:20pm: Keith Langlois of Pistons.com tweets that Detroit's side of the deal is official, and that Calderon will join the team in time for Friday's game. Since it was the Pistons-Grizzlies part that seemed to have hit a snag earlier, rather than the Raptors-Grizzlies end of it, the swap appears to be squared away. Pistons GM Joe Dumars has released a statement, as Vincent Goodwill of the Detroit News passes along (All Twitter links).

7:28pm: The trade call has ended, meaning the deal is now official, a source tells Ken Berger of CBSSports.com (Twitter link).

6:55pm: The trade call has been delayed slightly, but it's still going on, tweets Doug Smith of the Toronto Star, who adds that the deal is still going to happen.

6:18pm: Goodwill now hears from a source who says the trade will indeed go down (Twitter link).

6:06pm: A source tells Vincent Goodwill of the Detroit News there's "one hangup" in the deal, though Goodwill doesn't specify what it could be (Twitter link).

5:56pm: The Pistons' side of the trade has not yet been finalized, Aldridge notes via Twitter, though with the trade call scheduled in a few minutes from now, it's likely we'll soon have official word. Both Prince and Daye are inactive for Detroit's game tonight.

5:33pm: The Raptors will likely waive and buy out the rest of Haddadi's two-year contract, reports Ken Berger of CBSSports.com (Twitter link). Haddadi is making $1.3MM this year and is due a partial guarantee of $200K on his fully $1.398MM salary next year. Under terms of the new CBA, the Grizzlies will not be allowed to sign Haddadi again for one year.

5:13pm: The Grizzlies, Raptors and Pistons have all reached agreement on a three-team trade. ESPN's Marc Stein reported the Grizzlies have acquired Jose Calderon and Ed Davis from the Raptors in exchange for Rudy Gay and Hamed Haddadi. TNT's David Aldridge reports the Pistons will receive Calderon from the Grizzlies in exchange for Tayshaun Prince (Twitter link). Stein added that Austin Daye is also headed to Memphis, and noted the Grizzlies will get a second-round pick from the Raptors as well.

The trade call will be placed to the league office at 7pm Eastern, tweets Adrian Wojnarowski of Yahoo! Sports. When the trade becomes official, it will end several weeks of speculation about Gay's future in Memphis, as the Grizzlies look to avoid becoming a repeat taxpayer. It also ends months of chatter about Calderon in Toronto. The Pistons apparently beat out the Mavericks for the point guard, as Dallas refused to part with Vince Carter in any potential deal, Stein tweets.

The Grizzlies save significant money in the deal, as the combined salaries of Prince, Daye and Davis add up to $11.9MM, much less than the total of $17.8MM that Gay and Haddadi are getting. Daye can come off the books next season, as he's a restricted free agent this summer. Davis has one more season left on his rookie deal, at $3.15MM, and is set to hit restricted free agency in 2014 unless the Grizzlies extend his deal. Gay's contract runs through 2014/15, a player option season in which he's due to make $19.3MM. The Grizzlies are now $8MM under the luxury tax, which could give them more flexibility to make other moves this season, as Ken Berger of CBSSports.com points out (Twitter link). The Grizzlies will pay out $37.2MM less as a result of the moves, Berger adds.

Technically, the deal is actually a pair of two-team trades, rather than one three-team trade, notes Mark Deeks of ShamSports (Twitter link). The Raptors, operating exclusively with the Grizzlies, wind up with Gay's sizable contract, adding roughly $5MM to their payroll, which was at about $61.2MM. They're still well below the $70.307MM tax line, and figure to remain that way even when DeMar DeRozan's four-year, $38MM extension kicks in next season.

The Pistons, meanwhile, part ways with the last remaining member of their 2004 championship team, bringing in a point guard to mentor second-year man Brandon Knight. It also clears cap room, since Calderon's expiring $10.56MM contract will come off the books this summer, while Prince is signed through 2015.

5:01pm: If the Pistons are the third team in the deal, they're poised to send both Prince and Austin Daye to Memphis for Calderon, tweets Stein.

4:42pm: The Grizzlies spent the day calling around doing background work on Tayshaun Prince, according to Wojnarowski (via Twitter), so presumably Prince would be headed to Memphis if Calderon is sent to Detroit. Sam Amick of USA Today reports that the Celtics are another team in the mix to acquire Calderon.

4:35pm: If and when the deal is finalized, the Grizzlies are also expected to receive a second-round pick from the Raptors, according to Stein.

4:30pm: According to Stein (via Twitter), the Mavericks are another potential landing spot for Calderon, though Dallas is reluctant to part with Vince Carter, who the Grizzlies would want to replace Gay. Tim MacMahon of ESPNDallas.com made the case this morning for why the Mavs make sense as the third team in a Raptors/Grizzlies deal.

4:23pm: The Grizzlies and Raptors have a deal in place that would send Gay and Hamed Haddadi to Toronto in exchange for Calderon and Davis, according to ESPN.com's Marc Stein (via Twitter). An agreement hasn't been finalized yet because it figures to eventually include a third team, possibly the Pistons, that would acquire Calderon, says Stein (via Twitter).

4:03pm: Several sources tell Wojnarowski that the Grizzlies have a plan to move Calderon to a third team in the discussed deal with the Raptors (Twitter link).

3:48pm: As Tillery suggested, the Grizzlies would prefer to send Calderon to a third team in the trade scenario they're discussing with the Raptors. Ken Berger of CBSSports.com tweets that there are "several potential suitors" making a push for the point guard.

3:34pm: The Grizzlies appear to be moving closer to a deal that would include Rudy Gay, according to Ronald Tillery of the Memphis Commercial Appeal. Tillery reports that Memphis is weighing whether or not to pull the trigger on one of three different scenarios, including one that would send Gay to the Raptors. The Grizzlies have two other potential deals on the table if they and the Raptors can't reach an agreement by this weekend.

Adrian Wojnarowski is also reporting that the Grizzlies and Raptors are making progress on a potential trade. According to Wojnarowski, the two sides have discussed scenarios involving a third team in addition to straight-up scenarios. The Raptors would likely part with Jose Calderon and Ed Davis in any deal (Twitter links).

According to Tillery, in their talks with the Raptors, the Grizzlies are seeking a small forward, a draft pick, and possibly Davis. A third team may have to be involved to acquire Calderon and provide the small forward the Grizzlies are hoping to land. Darrell Arthur would not be involved in that hypothetical trade, says Tillery.

Wojnarowski adds in another tweet that the Grizzlies and Raptors are discussing the potential deal with their respective ownership groups, and could reach an agreement as soon as tonight.

TUESDAY, 9:57pm: Wojnarowski reports that the final hurdle for a deal that would send Gay to Toronto hinges on finding a third team to take Calderon's contract. He adds that within the deal's current framework, the Grizzlies are likely to receive another young Raptors player along with a future draft pick. Terrence Ross is not one of the names being considered, as the Raptors have reportedly deemed the rookie untouchable. 

8:11pm: Ryan Wolstat of the Toronto Sun says that the Raptors have little interest in taking additional salary in the form of Darrell Arthur's contract, and thus a third team would be needed if he were included into discussions. 

12:46pm: As they try to find a way to land Gay, the Raptors are engaging teams about a possible three-team deal, but are having trouble finding a taker for Calderon, according to Adrian Wojnarowski of Yahoo! Sports (via Twitter).

MONDAY, 7:00pm: The Grizzlies are engaged in active trade discussions with the Raptors centering on Rudy Gay, reports Marc Stein of ESPN.  Stein says that while the Raptors are Gay's most active suitor, no initial framework for a deal has been agreed upon.  Stein confirms that, due to last week's trade, the Grizzlies feel that they no longer must trade Gay and can instead wait and consider more fair value offers. 

The Raptors have been determined in their pursuit of Gay and also are interested in Grizzlies forward Darrell Arthur.  Toronto is offering up Jose Calderon and third-year forward Ed Davis as two of the main pieces in a potential deal.

Stein says that the Celtics have also inquired on Gay's availability, but was told that they balked at the prospect at giving up Paul Pierce in the deal.  In light of Rajon Rondo's injury, Stein was also told that Boston would be more likely to pursue Kyle Lowry and his cap friendly deal than Gay and his bulky contract.  As talks heat up, Stein says, more teams could become involved in a potential deal.

Grizzlies' coach Lionel Hollins, as well as several of the team's players, have reportedly lobbied management for a chance to play the season out as currently constructed.  But the Memphis front office is worried about its ability to improve the roster in future years, Stein says, and is subsequently seeking first round picks in any deal.

Led by Jrue Holiday, the 76ers remain three games out of the eighth seed in the Eastern Conference. Significant help in the form of another all-star caliber player could be on the way within the next several weeks, as Andrew Bynum has continued to make progress toward his goal of possibly returning to practice next week, notes Tom Moore of PhillyBurbs.com. The 7'0 center has been plagued by bone bruises in both knees since the start of the season. With that aside, here are more news and notes from the Atlantic Division: 

• Mike Mazzeo of ESPN New York reports that Nets GM Billy King will meet with owner Mikhail Prokhorov on Wednesday to discuss P.J. Carlesimo and the job he's done so far as the interim head coach. While Carlesimo has done an exceptional job after replacing Avery Johnson, Prokhorov is said to still be enamored with going after big names such as Phil Jackson and Jeff Van Gundy in the offseason. 
• According to A. Sherrod Blakeley of CSNNE.com, Celtics guard Rajon Rondo will get a second opinion on his ACL injury from Dr. James Andrews, who is considered be arguably "the best orthopedic surgeon in the business."  
• Mike Ganter of the Toronto Sun lays out the Raptors' top five pressing issues as they inch closer to the deadline, calling their interest in Rudy Gay the "most likely to come to fruition" rumor, examining the return of both Andrea Bargnani and Jonas Valanciunas from injury, Terrence Ross' progression into coach Dwane Casey's crunch-time lineup, and the continued acclimation of Landry Fields. With regard to Bargnani, Ganter thinks that Casey may have to provide a significant role at the expense of Ed Davis' minutes in order to showcase the 7-footer's health. 
• Eric Koreen of the National Post doesn't think that Gay is the cure-all answer for the Raptors, who still have many other important questions to answer regardless of whether they land him or not. Among those question marks involve the franchise's commitment to GM Bryan Colangelo, the need for more significant roster moves, and the struggles of point guard Kyle Lowry. 
• Doc Rivers doesn't appear too concerned about his players making an adjustment without Rondo, saying that a "no-point guard system" is something that the second unit has already found success with, writes Greg Payne of ESPN Boston. 
• Mike Woodson will place a higher priority on getting Knicks three point sharpshooter Steve Novak more involved in the offense, says Ian Begley of ESPN New York. 

Marc Stein of ESPN.com attended the NBA D-League Showcase in Reno, Nevada this week, where many NBA GMs and executives were present. He posted a roundup of trade-related chatter he heard during the event:

• The Raptors are making the hardest push for Rudy Gay, offering the Grizzlies a package that includes Jose Calderon and Ed Davis. Memphis is still undecided as to whether they will move Gay.
• There is a growing sense from front offices around the league that the Lakers will not ultimately trade Pau Gasol this season.
• Teams have continued to ask the Kings about DeMarcus Cousins, and were told that he is not available.
• A source told Stein that it is highly unlikely the Bucks will move Brandon Jennings before the end of the season.
• The Jazz are more likely to trade Al Jefferson than Paul Millsap, even though both are free agents this summer.
• The Hornets are not expected to trade Eric Gordon, despite previous rumors that he may be available.
• Despite his recent statement that he intends on staying retired, the Nets are still making a hard push to convince Phil Jackson to be their next head coach.
• Stein lists several players as having been made known to be available by their teams, including the Raptors' Andrea Bargnani, the Spurs' DeJuan Blair, the Cavs' Omri Casspi, the Rockets' Cole Aldrich, and the Bucks' Drew Gooden, Samuel Dalembert, and Beno Udrih.

A flurry of Rudy Gay rumors on Tuesday suggested that the Suns and Grizzlies were discussing a possible deal for Gay that could include Jared Dudley, and that the Warriors, Kings, and Celtics were among the other teams that had at least preliminary talks with Memphis. With six weeks still to go before this season's trade deadline, it's unlikely that the Grizzlies make a move this early, but the reports continue to pour in, so we'll round up today's Gay-related rumors right here, with the latest added to the top of the page throughout the day:

• The Nuggets also spoke to the Grizzlies about Gay, but those discussions appear to be fruitless, writes Sam Amick of USA Today. Amick adds that the Mavericks aren't currently pursuing Gay.

Earlier updates:

• The Raptors are seriously interested in making a run at Gay and are believed to be dangling young big man Ed Davis and Jose Calderon's expiring contract, reports ESPN.com's Marc Stein. Toronto previously made a run at Gay, offering packages headlined by Calderon and their No. 8 pick in last year's draft, which eventually became Terrence Ross.
• The Grizzlies haven't made a decision one way or the other yet on whether they'll trade Gay, says Stein, who adds that some rival GMs believe Memphis could wait until the summer to make a move. According to Stein, the Grizzlies don't intend to just move Gay's salary if it significantly weakens the team in the process.
• Responding to Stein's report, Ryan Wolstat of the Toronto Sun expresses uneasiness about the Raptors parting ways with Davis, and suggests that Ross may make more sense as a target for the Grizzlies (all Twitter links).
• At least eight teams have expressed some interest in Gay, tweets Steve Kyler of HoopsWorld. Kyler adds in a second tweet that the Grizzlies are "geniunely torn" on whether or not to move the veteran forward.
• If the Grizzlies have contacted the Timberwolves about Gay, it was a very casual conversation, says Darren Wolfson of 1500 ESPN Twin Cities. Finding a big man is the more pressing concern for Minnesota, according to Wolfson.

Marc Berman of the New York Post writes that Amare Stoudemire isn't quite ready to make his return for the Knicks just yet, citing that he is still "not 100 percent yet." Although he looked active during his scrimmage with the Erie Bayhawks today, Stoudemire feels that he still needs more practices and conditioning work before his return. You can find more of tonight's notable links from the Atlantic Division below:

• Coach Mike Woodson says that although Iman Shumpert took part in conditioning workouts, the young guard is still "a little ways away" with regard to his rehab (Christian Red of the New York Daily News reports). 
• Considering the Raptors' recent four-game winning streak, Mike Ganter of the Toronto Sun is wary of the possible challenges that Kyle Lowry and Andrea Bargnani will create for the team's current chemistry once they return from injury. 
• In a brief Q&A Twitter session with followers, renown NBA capologist Larry Coon acknowledged that Knicks rookies Pablo Prigioni and Chris Copeland will be restricted free agents this summer (Twitter link). 
• Stephen Brotherston of HoopsWorld notes that Raptors big man Ed Davis has made noticeable improvements and is beginning to progress into the talent that Toronto envisioned when they drafted him. 
• Chris Forsberg of ESPN Boston talks about why Jason Terry belongs in the Celtics' starting lineup.

The Raptors have completed just over a quarter of their season schedule, finding themselves tied with the Cavaliers for the second worst record in the Eastern Conference. Yesterday, we noted that GM Bryan Colangelo used the words "unacceptable" and "embarrassing" to describe his current thoughts on the team. During the first quarter of their game against the Clippers today, Colangelo followed up on those comments and touched upon other Raptors-related topics (Holly Mackenzie of Sportsnet.ca has the transcript). Here are some of the highlights:

On trade speculation: 

"We were talking to a lot of teams, what we always do, and it's a means of pursing avenues to improve your basketball team so if a deal comes along that makes sense, that is right and fits within the plan of this building process that we've been going through, we'll certainly take a look at it. If it can accelerate that process and if it fits then we'll look to address something. But nothing specific about any player right now. There's been a lot of speculation, a lot of rumors. Again, we're continuing to look at opportunities."

On Andrea Bargnani's consistency issues: 

"(Last year) it looked like he was putting up all-star numbers obviously for the first 15-18 games. He has not gotten back to that level. It looked that way early in preseason that he was coming back ready to become and perform at that level. But unfortunately we have not seen that consistency." 

On rookies Terrence Ross and Jonas Valanciunas: 

"(Ross is) a great talent and a number of the people I've talked to around the league think he's a great talent to have...he's been the recipient of some extra minutes because of some injuries. That's a good thing that will help us in the long run."

"(Valanciunas is) learning the nuances of what we're doing from a system standpoint, but also learning the game at the same time...Jonas is only 20 years old and really represents the future of this basketball team."

On second year big man Ed Davis: 

"We talked a lot about him getting off to a slow start because he didn't have the kind of development early that he needed early due to an injury and then also due to the lockout, but he had a great summer...But it really with him comes down to a focus on his effort level night in and night out."

On the team's struggles: 

" I do not believe that it's a talent issue right now; I do believe that it's about a team coming together. We're very young, we've had some injury issues, we've got the schedule, but we're not making excuses, we know there are some things that are broken and need to be fixed right now, but again, it's a lack of focus and a lack of attention to detail, I think more than anything right now."
