I could just go with the All-Star team like some, but lets assume there will be chemistry problems if you have Deron Williams sitting on the bench as your backup. Not that I won't have some nasty backups on here, but not the leagues 2nd best player at that position. A bit more realistic.
PG - Chris Paul / Ty Lawson
SG - Dwayne Wade / Jamal Crawford / Anthony Morrow
SF - LeBron James / Andre Igoudala
PF - Chris Bosh / Kevin Garnett / Anthony Randolph
C - Dwight Howard / Kendrick Perkins
The starting 5 needs no explanation really, the five best players at their positions in the NBA IMO.
Lawson learns behind Paul and improves on his play which has already shown a ton of energy and promise. Crawford provides dependable scoring off the bench and is a deep threat to bring in if you need one. Igoudala does everything and can play SF or SG. KG is a great backup, anchors the 2nd team D and mentors the whole team. Perk is a banger and great backup C.
The first lineup tries to play D and run the floor and play unselfishly. Howard gets you in transition by blocks or boards, Bosh benefits from the physical C and is better on D than some say, and then Paul/Wade/LBJ are absolutely unstoppable in the open court. Everyone besides Howard is a reliable scorer and Paul's passing ability probably makes Howard a reliable scorer (like it did for the far inferior Chandler) so literally anyone can hot and the ball should be passed to the open man.
So with the 2nd line up you have a great defensive frontcourt (Perk, KG, Iggy) that can hold it down and then a good all around PG with a lot of quickness and a SG who can create his own shot and fill it up in any number of ways. They have the same focus of running the floor and passing to the open man.
Randolph is your young project guy with a ton of potential who would learn from KG and Bosh. Morrow is a 3 specialist, currently the best in the NBA, who you can bring in if you need a shooter but also has room and potential to improve the rest of his game and would learn from the talent ahead of him in the lineup.
EDIT: I didn't really realize this was supposed to be like a current Olympic type team. But if so, basically the "Redeem Team" (minus Kobe
) plus a couple of guys on the current team like Rondo and Durant and you're all set.
