those on here who want to let Sully go are NUTS in my opinion. this guy has rare skills and is turning into a very reliable player: good option on offense; darned good rebounder. yet so many posters here are quick to write him off. the guy is a star in the making (see his stats vs Sacramento), and now that he's gotten the wake up call on fitness, watch him turn into an all star. he is a vital part of our future.
I don't think he's vital or even reliable, but I agree we'd be silly to let him or KO go (for anything less than a good/fair package). I'd much rather wait and see where they turn out as players.
Patience is a virtue.
Do people really not remember how we traded Joe Johnson and Chauncey Billups?
Even if we don't decide to keep them, we can possibly get a lot more value back in the future. We might get less if they turn out busts, but those are the exact type of calculated risks you need to take at this point in a rebuild.
If we're shopping players, I'd rather go with Zeller, who is a known player and unlikely to ever improve (same with Bradley and to a lesser extent Crowder/Jerebko).
