4. Bobby Petrino
As another college head coach way over his head, Petrino barely made it 13 games into his first season with Atlanta. Petrino continuously displayed poor clock management skills and alienated many of the stars on the Falcons team. After a pounding delivered by division rival New Orleans, Petrino decided to pack up the van and move to the University of Arkansas. He left a handwritten note in the locker room explaining his abrupt departure.
