Vigen has always been the hottest seat, specifically after the 3-0 loss to Missouri State to end the season in 2010.
Being a loyal alum definitely helped him keep his job when many wanted him gone. He is still the FU o-coordinator to this day.
I believe the d-coordintaor prior to Hazelton may have been fired, reassigned or asked to find another job. Cant remember who that was.
Ever since Hazelton, the FU Defense has been good to great.
