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).

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.

When the Timberwolves signed Kevin Love to a four-year extension, rather than a five-year deal, many assumed the team was saving its five-year franchise-player designation for Ricky Rubio. However, Britt Robson, who recently wrote about T-Wolves owner Glen Taylor for Twin Cities Business, hears from GM David Kahn that Rubio is likely to receive the same four-year offer Love did (Twitter link). Here are a few more links dealing with Western Conference clubs:

• Darrell Arthur, who was re-signed by the Grizzlies this summer, has suffered a leg fracture and won't be ready for training camp, tweets Ronald Tillery of the Memphis Commercial Appeal. It's another bad break for Arthur, who torn his achilles tendon and missed all of last season.
• Luke Babbitt isn't sure whether or not the Trail Blazers will pick up his fourth-year option for 2013/14, but he doesn't intend to let his contract become a distraction, as Chris Haynes of CSNNW.com writes.
• Eddie Sefko of the Dallas Morning News believes Dominique Jones, who also has a fourth-year option decision pending, could be a breakout candidate for the Mavericks.
• Heading into the season with a newly rebuilt roster and virtually no veteran players, GM Daryl Morey thinks his Rockets will be perhaps the league's most difficult team to forecast. Jonathan Feigen of the Houston Chronicle has the story.

FRIDAY, 5:03pm: The Grizzlies have officially signed Arthur, the team announced in a release.

MONDAY, 8:00am: Ronald Tillery of the Memphis Commercial Appeal identifies the third year of Arthur's deal as a player option, and says the contract will be worth slightly over $9MM.

SUNDAY, 9:32pm: The Grizzlies will re-sign Darrell Arthur to a three-year deal for between $9MM and $10MM total, tweets Chris Vernon of 92.9 ESPN Radio in Memphis (hat tip to John Hollinger of ESPN.com). The deal includes an option for the third year, but it's not clear from the report whether that's a team option or a player option.

Signing Arthur, coupled with an earlier agreement with Marreese Speights on a two-year, $9MM deal, would bring the Grizzlies closer to the approximately $70MM luxury tax line, as they already have $62.5MM of guaranteed payroll for 2012/13. 

JULY 13TH, 5:02pm: The Grizzlies have officially re-signed Speights, the team announced today in a press release.

JULY 6TH, 8:43am: Speights' two-year deal is actually worth almost $9MM and has a second-year player option, rather than a team option, according to the Memphis Commercial Appeal. As I noted below, the terms initially reported seemed awfully team-friendly, so this makes more sense.

7:48am: The Grizzlies and forward Marreese Speights have agreed to terms on a two-year contract, reports Chris Sherrington of the Memphis Flyer. According to Sherrington, the two-year deal is in the $7-8MM range, with a team option for a second year. While he didn't confirm the terms, Speights himself confirmed via Twitter that he and the Grizzlies have an agreement, tweeting "Yessir I am going back to #grizznation!! This year yessir!!!!!"

Speights, 24, was traded from the Sixers to the Grizzlies in January, and notched career-highs in PPG (8.8), RPG (6.2), and MPG (22.4), among other stats. The 6'10" big man was eligible for restricted free agency and received a qualifying offer from Memphis -- Sherrington puts the value of that offer at about $3.8MM, but I believe it was actually closer to $4.39MM, since Speights started 54 games for the Grizz, meeting the CBA's starter criteria. In that case, a two-year deal for $7-8MM seems like a very solid value for the club.

The Grizzlies aren't ruling out also bringing back restricted free agent Darrell Arthur, but will have to keep a close eye on their cap situation. If Speights has a first-year salary of, for instance, $3.5MM, the Grizzlies' guaranteed salary for 2012/13 will surpass $66MM, making it likely that the team approaches the luxury tax threshold of $70.31MM.

With the NBA's 2012 free agent period just two days away, teams continue to extend qualifying offers to free agents in order to make them restricted. If a qualifying offer is not tendered to a player eligible for restricted free agency, he becomes an unrestricted free agent.

Players who are tendered qualifying offers have the option to accept the one-year contract and hit unrestricted free agency a year from now, but the primary purpose of the offers are to ensure that the player's team can match any offers for him this summer. We'll track today's qualifying offer updates right here, with the latest added to the top of the page....

• The Cavs have made a qualifying offer to Luke Harangody, according to the joint Twitter account of Plain Dealer writers Mary Schmitt Boyer and Jodie Valade. The tender is expected to be around $1.05MM.

Earlier updates:

• The Jazz have tendered Jeremy Evans a qualifying offer, tweets Brian T. Smith of The Salt Lake Tribune. The offer should be about $1.05MM.
• The Bobcats have extended qualifying offers to D.J. Augustin and Derrick Brown, the team announced. Augustin's should be for $4,385,416, with Brown's valued at $1,085,120.
• The Cavs extended a qualifying offer to Alonzo Gee, writes Jason Lloyd of the Akron Beacon Journal. The tender is thought to be $3,342,175.
• The Celtics have extended a qualifying offer to Greg Stiemsma, tweets Chris Forsberg of ESPNBoston.com (Twitter link). It should be worth $1,054,389.
• The Lakers have extended qualifying offers to both Devin Ebanks and Darius Morris, according to Mike Trudell of Lakers.com (via Twitter). 
• Sonny Weems, who spent the season overseas, has received a qualifying offer from the Raptors, tweets Ryan Wolstat of the Toronto Sun. It should be worth about $1.09MM.
• The Grizzlies have extended qualifying offers to Darrell Arthur ($3MM) and Marreese Speights ($4.39MM), tweets Ronald Tillery of the Memphis Commercial Appeal. O.J. Mayo and Lester Hudson did not receive qualifying offers from Memphis.
• The Raptors have tendered Jerryd Bayless a qualifying offer, says SI.com's Zach Lowe. Bayless failed to meet the starter criteria, so he should receive a QO of about $4MM.
• The Pacers have extended qualifying offers to Roy Hibbert, George Hill, and A.J. Price, according to RealGM's transactions log. Hibbert's offer will be for about $4.39MM, Hill's for $2.27MM, and Price's for $1.09MM.
• The Bulls have officially extended Omer Asik a qualifying offer, according to RealGM. It's worth about $2.32MM.
• Courtney Lee has received a qualifying offer from the Rockets, according to RealGM. Since he met the CBA's starter criteria, it should be worth about $4.39MM.
• The Sixers have tendered a qualifying offer to Lavoy Allen, according to RealGM. The 23-year-old should receive an offer worth about $962K.

The Grizzlies have received a disabled player exception as compensation for losing Darrell Arthur, GM Chris Wallace confirmed to Ronald Tillery of the Memphis Commercial Appeal. Arthur had surgery in December to repair a torn achilles tendon and will miss the season.

Under the new CBA, teams are eligible to receive a disabled player exception worth the lesser of 50% of the injured player's salary or the amount of the non-taxpayer mid-level exception. In this case, half of Arthur's salary works out to just over $1MM, so Wallace doesn't have much flexibility.

"I can't say for certain if we'll use it," Wallace said. "It's fairly small as exceptions go. It's just one more piece to have. When you look at the restrictions around it, the probability is we won't use it."

The Grizzlies, who have until March 5th to use the exception, can only use it to trade for a player in the final year of his contract.
