Although the Mavericks/Lakers game tonight will have a serious impact on the race for the eighth playoff spot in the Western Conference, it's not the only noteworthy game on the schedule. The Knicks and Heat have comfortably clinched playoff spots, but New York is still vying for the second seed in the East, while the Heat are looking for a split of the season series with the Knicks. As we wait for those teams to tip off in Miami, let's round up a few odds and ends from around the NBA:

• Keith Schlosser of Ridiculous Upside passes along word that Henry Sims will leave the D-League's Erie BayHawks to play in the Philippines. The Hornets signed Sims to a 10-day contract a month ago, but decided not to re-sign him when the deal expired.
• Suns president Lon Babby is in the final year of his contract, and Scott Bordow of the Arizona Republic wonders whether he'll be back in Phoenix next season, since Babby's future with the team may be linked to the futures of head coach Lindsey Hunter and GM Lance Blanks.
• Grantland's Zach Lowe unveils his "I can't believe he's this relevant" All-Stars, which includes a number of players who will hit free agency this summer, including Luke Walton, Marco Belinelli, and Kenyon Martin.
• With Al-Farouq Aminu headed for unrestricted free agency in July, John Reid of the New Orleans Times-Picayune asks Hornets fans whether the team ought to re-sign him to a new contract for 2013/14.
• Mike McGraw of the Daily Herald makes the case for why it may make sense for the Bulls to re-sign Nate Robinson this summer.
• In his latest mailbag, Ira Winderman of the South Florida Sun Sentinel discusses whether the Heat will have the flexibility to bring back Chris Andersen next season.

Citing a source close to the team, ESPN New York's Jared Zwerling reports that the Knicks are considering adding a veteran point guard to supplement Raymond Felton, Jason Kidd and Pablo Prigioni.  While injuries have decimated their frontcourt, Zwerling says a lack of free agent options has led the Knicks to consider opting for guard help.

Zwerling indicates that the Knicks are ideally looking for a point guard that has some speed and quickness, in contrast to the wisdom and decision making of the older Kidd and Prigioni.  The source points to Delonte West, Sundiata Gaines and Jannero Pargo as options, with West being the most likely.  While West has some issues - as evidenced by his absence from the NBA this year - the Saint Joseph's product would join a veteran roster in New York.  Meanwhile, all signs point towards Pargo signing a 10-day contract with Charlotte tomorrow.  So unless that deal falls through, the Knicks would have to hope the Bobcats let him walk once his contract expires if they want to pursue him.

Two of those veterans are injured big men Amare Stoudemire and Rasheed Wallace, both out for the remainder of the regular season.  Zwerling says Mike Woodson remains committed to Wallace, probably making James White the odd man out should the team decide it needs a roster spot. 

Should the Knicks decide their need for frontcourt help is too pressing to consider anything else, Zwerling lists Henry Sims, Tony Battie, Josh Boone, Brian Cook, Dan Gadzuric, Troy Murphy, Ben Wallace, Hassan Whiteside and Sean Williams as potential targets.  While Sims provides the most intrigue of the bunch, Zwerling says the Knicks would prefer a veteran.

The Hornets have signed Henry Sims to a 10-day contract, the team announced in a press release. John Reid of The Times-Picayune reported yesterday that the move was expected. The 7-footer was with the Knicks in training camp this past fall, and before the Hornets got in the mix a source told Jared Zwerling of ESPNNewYork.com that the Knicks might entertain the idea of bringing him back this season.

The 22-year-old went undrafted this past June after four years at Georgetown. Sims has seen extensive time with the Erie BayHawks of the D-League this year, starting all 36 of the team's games and averaging 17.1 points and 9.0 rebounds per contest. When Jimmy Smith of The Times-Picayune reported Friday that the Hornets were looking for a center, I speculated that Sims might be someone they consider.

New Orleans made liberal use of 10-day contracts last season, and with big man Jason Smith out for the season with a torn labrum, Luke Adams of Hoops Rumors wrote that more short-term deals might be coming. The addition of Sims gives the Hornets 14 players on their roster, leaving one more spot open should they decide to pursue more depth.

The New Orleans Hornets are expected to sign center Henry Sims of the D-League's Erie Bayhawks to a 10-day contract, John Reid of the Times Picayune reports.

Following the announcement that Jason Smith would miss the remainder of the season with a torn labrum, it was reported that the Hornets were looking to add another big man.

Sims has averaged 17.1 PPG and 9.0 RPG with the Bayhawks this season and has never played in an NBA game.

Alex Kennedy of HoopsWorld says that last week's quiet deadline could lead to a noisy offseason this year, with quite a handful of those who were rumored to be moved set to hit free agency. Kennedy provides a list of this summer's top 20 free agents along with a primer of each player's situation to boot. One interesting situation involves Oklahoma City's Kevin Martin, who has already been given the impression that the Thunder would like to keep him for the long-term. However, Kennedy opines that a strong post-season could increase the shooting guard's stock to the point where Oklahoma City may have to let him go - as they did with James Harden - if his price tag becomes too high. Here are a few more tidbits we've gathered up from the NBA this evening:

• The Pistons figure to have the task of re-signing Jose Calderon as one of their top priorities this summer, writes David Mayo of MLive.com. However, Mayo thinks that the team's lack of practice time has hindered Calderon's efforts in trying to become acclimated in Detroit. 
• Channing Frye discusses the mental toughness he's developed as he continues to sit out from a heart ailment that caused him to miss the season (Stefan Swiat of Suns.com). 
• While the Lakers' regular season has been disappointing so far to say the least, Steve Nash tells Sam Amick of USA Today that if given the opportunity to revisit last year's offseason: "Ten out of ten times, I make the same decision again." Nash's agent, Bill Duffy, thinks that the point guard would have considered retirement if they were unable to get a deal to Los Angeles done. 
• Don't expect anyone from the Magic roster to shake free anytime soon, as Josh Robbins of the Orlando Sentinel (via Twitter) says that the team isn't planning to buy out or waive anyone before the March 1st buyout deadline.
• Newly acquired Tobias Harris offered his thoughts on being traded to the Magic and the opportunity that lies ahead for him on a young team looking to build for the future (Steve Kyler of HoopsWorld reports). 
• Current ESPN analyst and former NBA head coach Flip Saunders remains open to coaching again, whether it be in the NBA or the college ranks, writes Kent Youngblood of the Star Tribune: "I'm keeping my options open...If the right situation comes along? I'll evaluate that. I want to be able to build something, want to go to a place where something can be accomplished.''
• D-League standout Henry Sims of the Erie Bayhawks could be given a chance to join the Knicks depending on how Kenyon Martin fares during his 10-day contract, notes ESPN New York's Jared Zwerling. One NBA scout thinks that Sims has played well enough to be on an NBA roster next season at the very least.

With Rajon Rondo out for the year, two of the Celtics' Atlantic Division rivals are in position to give Boston a run for the eighth and final playoff seed in the East. The 76ers are 2.5 games back of the Celtics, while the Raptors are five games back, and both teams hope to have injured players returning to the floor in the next few weeks -- Andrew Bynum for the Sixers, and Andrea Bargnani and Jonas Valanciunas for the Raptors. Here's the latest out of the Atlantic:

• As the summer approaches, the Sixers are hoping to get a better idea of whether it's worth the risk to lock Bynum up to a long-term deal, as GM Tony DiLeo tells TNT's David Aldridge. "We don't have enough information," DiLeo said. "We want to re-sign him. We plan on re-signing him. We made the trade having him as part of our future. That's the direction we're going in right now and we don't have enough information to make a decision."
• The Sixers constructed their roster with the intention of having it revolve around Bynum, so DiLeo acknowledges to Aldridge that the team would have to employ a different approach if Bynum is not re-signed: "We have a good young nucleus, but yeah, we'd probably have to go in a different direction and use our cap room and the draft and trades."
• Zach Lowe of Grantland looks into some potential trade partners for the Celtics if they decide to shop Paul Pierce, noting that they'd likely only be able to land either a good first-round pick or a blue-chip guy on a rookie contract, rather than both. According to Lowe, the Raptors may be the most viable and intriguing match for Pierce and the C's.
• Also within Lowe's piece, he notes that executives around the league view Rondo as a max-contract type player.
• Jared Zwerling of ESPNNewYork.com explores the possibility of the Knicks calling up D-League standout Henry Sims, who was in camp with the team in the fall.

The latest on various moves and happenings from around the D-League on Sunday afternoon:

• The Los Angeles D-Fenders have acquired former NBA player Lazar Hayward, reports ESPNLosAngeles.com's Dave McMenamin.
• Gino Polato of Ridiculous Upside looks at former Raptors center Solomon Alabi, currently with the Idaho Stampede, as a player who could help an NBA team in need of big-man depth.
• David Scrivenes of Ridiculous Upside lists D.J. Kennedy, Henry Sims, and Keith Benson as D-League players with the potential to be called up to the NBA.

The Knicks waived four players to get down to the 15-man roster limit today, cutting ties with Oscar Bellfield, John Shurna, Mychel Thompson and Henry Sims, as Jeff Zillgitt of USA Today reports (Twitter link). Shurna and Sims had partial guaranteed of $50K, while Bellfield's and Thompson's contracts were non-guaranteed. The moves likely mean Chris Copeland, who has a non-guaranteed deal, will be on the Knicks opening-night roster.

The Knicks have officially signed four players to contracts that include training camp invites, according to a team press release. We heard yesterday about the team's deal with John Shurna, but the other three names are new -- the Knicks have added center Henry Sims, guard Oscar Bellfield, and forward Mychel Thompson.

Sims, a seven-footer out of Georgetown, was ranked as the seventh-best center in this year's draft by ESPN.com's Chad Ford after averaging 11.6 PPG and 6.0 RPG in his senior year, but went undrafted. Bellfield, a senior out of UNLV, also went undrafted in 2012.

Thompson, meanwhile, is the only player of the four with any NBA experience, after a brief stint with the Cavaliers in 2011/12. Klay Thompson's older brother appeared in five games for Cleveland last season, starting three. He's a year removed from going undrafted out of Pepperdine, where he averaged 14.6 PPG in his senior year (2010/11).

According to Ian Begley of ESPNNewYork.com (via Twitter), all four players worked out for the Knicks in the spring, and will be fighting to earn one of the team's final roster spots. The Knicks now have 19 players under contract heading into camp, including up to seven believed to be on non-guaranteed deals. For the players that don't earn an NBA roster spot, a place on the Erie BayHawks, New York's D-League affiliate, could be in the cards.
