May 30: Jim Tressel’s 10 years as head coach of Ohio State ended when he stepped down amid allegations he wasn’t cooperating with an NCAA investigation into whether he allowed players to play while ineligible. After an initial suspension, Tressel resigned after meeting with Ohio State president Gordon Gee and athletic director Gene Smith. He’s third on the list for most games won by an Ohio State coach.
