Just gave this a thought for a bit. Let's say Pierce re-signs for the MLE (I think he would if the following scenario happened). If we let Ray go, and with Sheed retiring, won't we have enough for Wade? Just think about it.
Rondo
Wade
Pierce
Garnett
Perkins
That's even better than the Bulls if they get LeBron AND Bosh!
Only thing is, though, is Pierce loyal enough to take a salary cut for the better of the team?
