Tyreke Evans would be great.
Cousins ... I think I will pass on him. I think he is extremely overrated to begin with (is there anyone that turns the ball over as much and as stupidly as him?) and he is a TERRIBLE shooter. Everyone gets hot and bothered that he scores so many points, without realizing how many shots he is jacking up to do so. He really is NOT a good scorer (42% is a criminally low shooting percentage for a big man). I do admit his rebounding is sorely needed, and he isn't a slouch defensively ... but unless he can be coached better on offense I don't want him. His history shows him to be such a headcase I don't trust him to be able to learn not to play like an idiot. Maybe, though ... but Cousins is a project NOT a win-now proposition. He has to change his game too much to be a meaningful contributor in our system, IMO.
Evans or Thompson seem like they will work better for THIS season. If we are talking about a project, I think Cousins is intriguing, but by no means the sure-fire star some people seem to believe he is.
