I don't understand the Cavs offense at all.
You have a semi-skilled big man in Mobley. Skilled in terms of handles, driving, finishing, little short shots. Small big of a midrange game. But you use him like he is Tristan Thompson. Why?
You gotta get him involved in the game. Use dribble hand offs. Use short rolls on the PnR. Get him moving. Get him the ball on the move. Let him attack an off balance defense.
Mobley is the not the type of player who can beat people with muscle. He has to beat people on the move with his quickness. He has to have guards who get him the ball on the move. Neither D Mitchell or Garland do that.
Nor does the offense give Mobley opportunities like this. They treat him as a non-skilled garbage man like Tristan Thompson. Play off ball. Stay away. Maybe a PnR roll opportunity. Often just stand on the baseline and avoid the ball. Wait for a rebounding opportunity.
It is awful to watch.
