The Cavs should shake it up. I think Jarrett Allen to San Antonio gives Wemby a legit big to play next to, taking pressure off of him in the paint. Allen is also a very good rim protector and perimeter defender, further shoring up that defense. For the Cavs, Vassell slots in as a Strus replacement, just younger and better. Trey Murphy gives them a young wing who can score and defend. Cavs also get off Schroder.
