No. 4: Kalani Sitake, head coach
This is a crucial year for Kalani Sitake as the head coach of the BYU football program. Year 1 was nearly spectacular, just eight points from being an undefeated season. Year 2, however, was one everyone wants to forget. Sitake made a number of changes to counteract the issues that caused the dismal results, but only time will tell if those adjustments will pay off.
