David Cutcliffe won’t return for a 15th season as Duke’s football coach. The school announced a “mutual agreement for separation” following the Blue Devils’ winless Atlantic Coast Conference record. The announcement came a day after the Blue Devils closed a three-win season with a 47-10 home loss to Miami. That marked the first winless league slate for Duke under Cutcliffe, who took over in December 2007. Cutcliffe had transformed Duke from one of the nation’s worst programs into a regular bowl contender. But the Blue Devils slid badly over the past two seasons. Cutcliffe had one year left on his contract.
