I don't get where people presume IT and Cousins don't have a good relationship. They still do, and frequently message each other on Twitter.
Cousins may have inherently took shots at IT, after his departure, with his comment about how ball movement has been better ever since he left. But hes just simply stating the facts. When you have players like Gay, Cousins, and IT who all have a really high usage rate, its hard not to disagree with that statement.
Other than that, Cousins has expressed and always promoted IT in a good way.
