I'm going on the premise of what they were like when they were on the Dream Team, not at their prime
-----------------------------------------------------------------------------------------------------
PG John Stockton - Indiana Pacers - In the half court: Pick-and-roll with Jermaine O'Neal. When you run, you have finishers in Granger, Jackson, O'Neal, Daniels, and the rooks. Seems like he would thrive in and enjoy playing in Rick Carlisle's methodical offensive attack with the defensive intensity Carlisle demands.
PG Magic Johnson - Miami Heat - A reunion with his favorite coach! They need a real point guard and someone who can run the break as easily as realize its time for Shaq to see the ball. I like Westkoast's pick of Dallas, I just see Magic running Avery Johnson out of town for a guy like....well....Pat Riley.
SG Clyde Drexler - Orlando Magic - Clyde was a scorer and active defender with a decent outside shot. He could thrive anywhere but with the Magic, he has two things he had in Houston. A low-post threat, a big man that does the dirty work, and a point guard more suited to spreading the defense with a shot than attacking with dribble penetration -- Clyde will be doing the latter.
SG Michael Jordan - Philadelphia 76ers - More than anything this team needs a guy who can finish games and demand effort on defense. They can only hear so much from Mo before a "true" leader takes upon himself to own the team. In Iguodala, he has a multi-talented, multi-faceted forward who is an awesome defender and can handle the offense (hello Pippen). In Korver, one of the best outside shooters in the game (hello Paxson-Kerr). In Dalembert, a fast, quick guy with long arms who does the dirty work (hello Rodman). In Webber, a rebounder with a decent mid-range game and some nice passing skills (a little like Grant). I think he would try to convince the team to fire Cheeks and hire a Mike Brown-type and trade Webber for somebody like Kaman or Haslem.
SF Chris Mullin - Milwaukee Bucks - Adds to a potent offensive attack while at the same type giving the team more reliability than Simmons and puts Patterson back on the bench where he can focus on being a defensive specialist. You've heard of Run-TMC, you'd have Run-MMC with a good-passing post-threat to boot.
SF Larry Bird - Los Angeles Clippers - Bird would be a great second scoring option (since he is now advanced in age) on a defensive-oriented team. You have the reliable outside shooting that came and subsequently left with Radman. A guy who can handle the offense, play great team defense, and generally pull the guys together in the locker room instead of apart (like Magette).
SF Scottie Pippen - Houston Rockets - This team needs someone to be able to run the offense in addition to Tracy McGrady. Instead of a Point Guard, why not a tall, lanky defensive-minded forward who brings the ball up the court and distributes giving Tracy the energy to finish the game and raise his efficiency. When all else fails, dump in to Yao. A little redundant with Shane Battier but I think Shane could be moved to Power Forward and you'd a heckuva imposing lineup size-wise.
PF Christian Laettner - San Antonio Spurs - Laettner is a bad player on a bad team and a good player on a good team. He needs a good, solid team with a good, solid game plan. Laettner can play foil for San An's big three while doing a lot of what Oberto, Elson, and Butler do more efficiently in one package. He's also another offensively intelligent player which always helps make up for Popovich's deficiencies in that area.
PF Karl Malone - Sacramento Kings - A leader who leads by example (without fanfare or ultimatums) for this ball club desperately in need of stable leadership and a little bit of reliability with injuries and such. Karl Malone's spleen could be hanging out, he's giving you 82 games. I think Bibby would wise up and learn the pick-and-roll with Malone (a guy who'll take the ball and dunk it on people) rather than Miller (a guy who'll pop the shot or work it around with a pass). A gifted SG, in Martin, who can handle the ball and keep people honest. And Brad Miller himself who, along with Malone, will form the best passing front court in the NBA. Kenny Thomas and Shareef can be what they are, bench role-players. Which leaves us Ron Artest, if he buys into the idea that its Malone's team, keep him. He starts causing trouble, send him packing...maybe to the Clippers for Quinton Ross and a 1st round draft pick.
PF Charles Barkley - Toronto Raptors - Would absolutely decimate people in Toronto's open court attack. He will bang around the low block and grab a ton of rebounds, keeping Bosh fresh to work in the half-court offense and keep his minutes down a bit. Obiously this hinders the development of Bargnani but I think he should develop nicely as instant offense off the bench. Barkley will be Bryan Colangelo's type of big man.
C David Robinson - Utah Jazz - Robinson will make up for all (and its quite substantial) of Carlos Boozer's defensive deficiencies. A hardworking, cerebral player who'll understand Sloan's system and work seamlessly in the motion offense and pick and roll. What this does is make Okur a little redundant and you can trade him for a SG (like Kirk Hinrich or Brandon Roy). What it also does is add someone with great hands who'll be able to catch the passes Kirilenko and Williams like to zip down.
C Patrick Ewing - Seattle Supersonics - A real low-post threat. Essentially they'll finally get somebody who'll do all the things that they wanted someone to do when they drafted Nick Collison and then Robert Swift and then Johan Petro and then Mohammed Sene and then signed Chris Wilcox. Ewing will be the Ying on the inside to Allen and Lewis' Yang on the outside. Sould finally be a complete team.
