On the flip side, it doesn't matter that Thomas Robinson was a top five pick if he can't play. Same goes for Thabeet and the countless other busts in the top end of the draft. Once you get into the NBA it just doesn't matter.
I'm assuming you were half joking about the 'veterans' move. I couldn't think of a worse get for Cousins, unless those 'veterans' are All-Stars, and they won't be. 41-41 gets you nothing in this league. I'd take this deal with Boston over an Afflalo / Harrington deal every time. Am I jaded? possibly. I've watched just about every NBA game Bradley and Sullinger have played, along with every one of Green's games since he's been in town.
Of course, every team would want to steal Cousins, I just don't think this is a steal. Not with who DeMarcus Cousins is right now. Cousins is talented, we all know this. He has is off the court stuff that I'm personally tired of talking about so I won't mention it further, but he has some glaring weaknesses in his game. He is an awful defender. Awful might not be strong enough. He also has a terrible FG%. Those are two things that as a center on a playoff team he's going to need to figure out. We are on year 3 with him, and those are two parts of his game that have been worse this year then they have ever been. His game ON the court is regressing, and his issues off the court are progressing. He isn't a sure thing anymore.
For the record, I would hold onto him. I wouldn't do the deal unless I'm hell bent on trading him, and I would think it is a fair return considering the circumstances (those circumstances being that we decide we ARE trading him / he ask's to be traded, which isn't that unlikely). Our issue right now is that we lack leadership from the ownership down. Does anyone have any confidence in this franchise? Does anyone think these guys will lead Cousins to his reaching his full potential? I don't. And I'm not sure Cousins can get there on his own.
Guys like Sullinger / Bradley / anyone else who's not DeMarcus Cousins - they can get their **** figured out without any help from the coach / front office / ownership. Cousins needs to be molded by the right people ... people we don't have right now.
