Tuiaki will continue to hold the BYU program back, and Kalani will never get rid of his best friend and cousin who has been with him his entire life.

The BEST hope for BYU is for Kalani to reduce the amount of influence Tuiaki has on the defense.
Remove the responsibility of game planning from him. He's just not good enough at it and after seven seasons he's not getting better. Remove the responsibility of play calling from him. He's just not good enough at it and after seven seasons he's not getting better.
Remove the responsibility to develop defensive linemen from him. He's just not good enough at it and after seven seasons his players are not getting better.
Kalani may even need to remove the responsibility of recruiting players from him. After seven seasons his position group is not getting better.
