A big factor in the decline is assistant coaches. While many of us are aware of how bad of a hire BVG was for DC, Petrino also hired his son and 2 brothers-in-law as assistant coaches. I believe 2 of the 3 family members/coaches had no previous D1 coaching experience. UL was successful when Todd Grantham (now at Florida) was the DC. They had excellent defense and other decent assistants. It seems the downfall began with the loss of quality D1 assistant coaches. Petrino as well as the 3 family members were let go today.
