He’s zero threat to dribble/drive and we don’t run him off screens, which makes him essentially useless on offense. Plus, it’s not like he’s that much better than our true wing shooters.
If we replace him with someone that can dribble/drive that isn’t a viable catch-and-shoot threat outside of the arc, there is one more defender with a foot in the paint waiting to Mark Adams anyone that attempts to drive. Even if Jaz never touches the ball and stands in one place, it opens the floor.
This doesn’t account for the assists, tip-out rebounds, and charges that he’s good for each game. He’s an important piece.
