Knell will get consistent minutes primarily as a spot-up shooter. He should get a lot of clean looks because of the very athletic players BYU has inside. I expect Knell to shoot a higher percentage than the last 2 years and to be a significant contributor.
Saunders will also get consistent minutes, not only because he's a talented player, but because he has a motor that runs non-stop. Whenever he's in games good things tend to happen.
My bigger question than what will happen with Knell and Saunders is how this team mesh overall, and how will players react who don't end up getting the amount of PT they think they deserve.
