...coach can push guys to play insane defense without holding anything back. No need to worry about foul trouble or getting tired. We can really step up our intensity and be more of a full court team on D as well as on offense pushing transition more.
As you noted, it will be a real challenge for coaches to keep players happy and focused on team goals if they're not happy with the role they have, the touches they're getting or the amount of playing time they're getting.
It's a credit to how great of a person Coach Pope is, guys are willing to give up significant roles on other teams in order to be part of his team at BYU.
