Was it though? I think Blake handled it the best he could. He asked Quick if he was retiring after his contract, he said no, so he was traded. It isn't like Quick was winning games for the Kings, he was clearly declining and wasn't working here.
I have issues with alot of what Blake has done/is doing but his handling of Quick was the best he could do with a bad situation. I only wish he'd done it a year or two earlier when Quick had higher value.
Lastly, Quick didn't handle the whole thing great himself, essentially refusing to play for Columbus and forcing a trade to a contender. Spoke volumes of both his work ethic and his cockiness.
