Hawk, a senior, led the Buckeyes in tackles in each of the last three seasons. This season, he rang up 60 solo tackles, 7½ sacks, one interception and scored one touchdown. He is the first Buckeye finalist since Andy Katzenmoyer in both 1997 and 1998, and the fifth OSU player to win the award and joins former Buckeyes Jim Stillwagon, who won the inaugural award in 1970, John Hicks, who won in 1973, Chris Spielman, who won in 1987, and Orlando Pace, who is the only repeat winner in 1995 and 1996.
Hawk beat out Louisville defensive end Elvis Dumervil, Texas defensive tackle Rod Wright and Penn State linebacker Paul Posluszny.
Georgia's David Pollack was named winner of the award last year.
