I'd guess Pikiell wants to play man as much as he can. I am just looking at a small step backwards defensively. All things equal no more than a basket per game.
Just thinking about the players that the program lost, and think their defense can be replaced.
Pikiell did say Mathis can be a great defender, he just has to realize it. Something to those terms. Kiss will give a lot of effort, and rebound well.
Baker should be able to do what Sanders did at a more consistent rate. Sanders was not an above average consistently.
