Coordinators is lame. Kalani is responsible for the team, he should have 100% freedom to fire/hire anyone he wants. And we should be slamming him for the results not the coordinator. All the Tuiaki hate should be directed at Kalani. (But that would be insane right now since we are 21-4 the past 2 years) so we scapegoat Tuiaki.
Lastly, and most obviously, BYU has had great teams the last 2 years. Any talk of firing coaches is nonsense right now. Consistency in coaching is HUGE, don’t throat it away lightly chasing something that might be better.
