ASU, why give up our $2 mil Voskul exemption and a 2nd rounder for Payton, when we can get him at the vets min as it stands now. Boston IS NOT going to get him back. He won't go back to the Lakers becaus ehis stint with them wasn't what he likes (i.e. Triangle, Kobe, Phil), and Sacramento is not going to be a contender. So, the Suns are the only other team he mentioned as a possibility, therefore he should be a no brainer to sign for the Min.
Now, with that said, we could do the exemption plus Barbosa for Walker (S&T @ 5.8 mil for 2-4 years. Walker could flourish in our system, he can play the 3 behind Marion, the 4 behind Amare and KT. He spreads the floor with the 3 ball, he posts with the best of them, and he can board. Good looking out on that front though ASU. Boston might be more inclined to do a deal to a Western Conference team than to do a S&T with the Eastern Conference.
