For any player on the roster, you have the option of trading him straight up for the nth pick in the 2012 NBA draft. For what value of n would you not make the deal?
I think it's been established that most people here would happily trade Dooling for the 60th pick (the last of the second round) and probably the 90th pick if the NBA added a third round. I think almost everyone would trade Rondo if n=1, some would balk if n=5, more if n=10. I'm not sure if anyone values Rondo so poorly that they would swap him for the 20th pick. Some people say they would want to get anything for the expiring contracts of Garnett and Allen, but I've also had posters say that they would rather just keep Ray if a middle second round pick (and another expiring contract) was the likely return for him.
I think the most interesting players to play this game with are Rondo, Pierce, Allen, Johnson, and Bradley.
