It seems like Cubes doesn't give a whole damn about the Mavs anymore. Sure, he still has a deep affection for them, but the fire seems to be gone since the championship.
If he is either unwilling or unable to get Dirk a good cast, he can s*ck it. F*cking shooting a SharkCvnt episode instead of talking to DWill. Wasting at least two years of Dirk's prime.
