Westbrook can be fun to watch, but I'm not sure he's some one you roll the dice on. KD left in some parts because of him, what does that say.
IT and Westbrook don't work together, so IT would be gone, and over the short 1.5 years he's been here, he's been the best ambassador for the C's and talking to other players. I'm not sure DA would move him, at least not right now, not for a rental and blot player.
