KNOXVILLE, Tenn. — Doug Atkins, a defensive lineman who earned induction into both the Pro Football Hall of Fame and College Football Hall of Fame, has died. He was 85.

Robert Shelton, a co-owner of Shelton-Hunt Funeral Home in Humboldt, Tennessee, said that Atkins died Wednesday morning of natural causes at Fort Sanders Regional Medical Center in Knoxville, Tennessee.

Atkins was a four-time all-NFL selection who made eight Pro Bowl appearances during a 17-year NFL career with the Cleveland Browns, Chicago Bears and New Orleans Saints. His 6-foot-8 frame created major matchup problems for opponents.

“He was just a vicious pass rusher,” said Hall of Famer Mike Ditka, a former Bears teammate. “He’d take the tackle all the way back to the quarterback and knock them both down, things like that. He had a great wingspan. He just played the game hard. He played the game the way you were supposed to play it.”

Atkins wreaked havoc with his size.

“He looked like Michelangelo’s David physically,” said Bill Curry, a former NFL offensive lineman who played against Atkins. “That’s what he looked like. Just huge. He was perfectly proportioned.”

Atkins was inducted into the Pro Football Hall of Fame in 1982 and the College Football Hall of Fame in 1985.
