Williams' effort dissapointed me last year. I saw him far too many times looking at loose balls, not going after them. There's no excuse for lack of effort, regardless of whether he's coming off the bench or as a starter. If you talk about "team culture" you better back it up and have players who are fighters with a a passion for winning, not prima donna's. Also, he doesn't have the fluidity you want in a 3, nor the length you want in a 4. He does seem to be the classic tweener. But my main concern with him is effort. If Gay leaves, there's no way you want him as the starting 3. That's a big step down.
I concur with the sentiment that if IT leaves you are probably in a similar situation you had with Tyreke - not getting back equal value in return on a sign and trade. If Tyreke got us Vasquez, what's IT going to get us? Based on the Vasquez trade, I'd rather get as many draft picks as possible in the lower part of the draft.
The only thing I'm really positive about right now is the news about the number of good 3s being available on the market. There are several of those 3s I'd rather have than Gay because I think they would fit better with Cousins, Parsons being one of them. So maybe, just maybe, Gay opting out will be a good thing and the Kings can get a better fit at the 3.
