He played college football at the University of Tennessee and served as an assistant coach at the University of Alabama under Bear Bryant. Donahue and four other men, Pat Dye, Bill Oliver, and Paul Bryant, created the multiple defense scheme that allowed the players to switch defenses quickly. The 4-3 and 5-2 schemes are still used by NCAA and NFL teams today."@en . "Donahue, Ken"@en . . "1925Z"^^ . "Ken Donahue"@en . "American football player and coach" .
