Carr walks off the field after a loss to Ohio State on Nov. 17, 2007 in Michigan Stadium. Carr told his team and his staff Nov. 18 that he was retiring as the Wolverines' head coach. He won five Big Ten championships, guided the Wolverines to a bowl every season, and will retire as the third-winningest coach (121-40) in the school's history, trailing only Bo Schembechler and Fielding Yost.
