Depends on the type of player. I sure as hell wouldn't give up on an athletic 7 footer, but sometimes they just aren't there mentally yet (in the case of Whiteside) and they need a kick in the ass or a reality check (happened to Danny Green too), but a tweener who doesn't play much defense and hasn't shown an improvement in offensive skills in 3 years? I'd be more inclined to look for other opportunities, which is why I think he hasn't stuck around on a team yet, though I'll give him a pass for getting traded by the Rockets for cap to sign Dwight. And nowhere did I say I am giving up on T-Rob, I'm just saying I think at his very best he'll give you the same amount of production in more minutes and hit close to his current per 36 numbers, which is essentially what Tristan puts up per game.
