what I want to say is that he just isn't a very talented player. if he would focus on the typical role player qualities, he would be useful.
remember all the talks about Devin? they are more or less the same players, with the difference that Devin is slightly better in most aspects and the difference that Devin is much better in understanding his role.
before I dream of adding Wilkins, I dream of bringing back Devin anytime.
if Wilkins was a part of this team, people would get very very disappointed immediatly.
that doesn't mean that there wouldn't be a nice scenario, if we look at the Sonics. it's Collison. not that they activly try to get rid of him, but considering their rebuilding process it's quite possible, that Presti wants to get rid of his long term contract. if he could be had for expiring contracts (plus a pick if needed), then this would be a helpful addition in the current situation. and IMO his smart game and passing ability should fit well alongside Tim. and the fact that he is one of the best offensive rebounders in the league, would provide a wellcome upgrade in this department.
(if it was necessary to swallow Wilkins in such a trade....so be it)
