He's a soft player. Always has been. As someone said above, he fills no holes, other than some bench scoring. If everyone's healthy, he's on the bench, and no, he can't file Theis' role. Theis is a much tougher player, much better rebounder and defender.
If you trade for him, it's because you value him as an asset, possible predicate to a future deal, not because he fits the current team.
