BYU struggles to recruit corners and defensive ends, but you have a plethora of linebackers and safeties. Him being willing to swallow his pride and install a defense that works for BYU was very smart and worked great for him. I hope Kalani sticks to the 4-3, it doesn't work as well for BYU's recruiting strengths (although that might change with Kalani as the HC, if he gets the chance).
