I have to say 1...woody is the only legit shot at this point.
Marble is the next most likely especially if his 3 pt shot keeps developing and he keeps showing this latest efforts on the defensive side. But he needs 1 more yr of this to have a shot.
White is the next likely canidate. But he has more than marble to sure up. He either needs to develop a better wing game so he can be a 6'8 wing or and size and more back to the basket abilities to be a legit 4. Though I feel his game is tailor made for the 4 spot in europe.
The rest do have much shot...jok and uthoff are the other likely possibilites from next yr's roster...jok more so than uthoff (imo) but both have skillsets that can develop.
