There are a lot of good players to unlock in this game, but I'm really missing a few... 
 
- Shawn Kemp 
- Gary Payton 
- Chris Webber
 
...and others.  I really wish Kemp and Payton were in the game.  I know Seattle doesn't have a team anymore, but they seriously couldn't just put them either with the Thunder, or just give them their own team?  The Sonics were my team to play with back in the day, and I really wish they were in this game.   Also kinda wish Harold Miner was in the game too, but that's probably just me...
 
Anyone else wish some other players were available to unlock in this game, that were in past games?

-Spud Webb 
-Gary Payton

Charles Barkley. 

Penny Hardaway should have been in it.

" Charles Barkley.  "

" @Axxol:  Spud Webb is in it. "

As mentioned earlier, Shawn Kemp and Gary Payton would be pretty cool to play as.  I'd also be up for some Charles Barkely and Penny Hardaway as well.

David Bowie
Sting
Bono
Jonny Rotten (and he would fucking do it too) 

I should mention at this point that I actually like David Bowie. not so much for the other guys (thought they were all in great bands)
 
EDIT: Oh wait, ones that were in past games. Well the Sonic Youth then.
