Willy Robinson steps down as Arkansas defensive coordinator

FAYETTEVILLE, Ark. (AP) - Arkansas coach Bobby Petrino says

Razorbacks defensive coordinator Willy Robinson has resigned.

Robinson is the third Arkansas assistant coach to leave the

school in the last two days. Former offensive coordinator Garrick

McGee was named the Alabama-Birmingham head coach on Monday, and

former special teams coach John L. Smith left to coach at Weber


Robinson led the Razorbacks defense for four seasons, coming to

Arkansas after serving as the secondary coach for the St. Louis

Rams. The 55-year-old also spent one season as the San Francisco

49ers defensive coordinator in 2004.

The Razorbacks were 72nd in the country in total defense in

Robinson's first season in 2008, falling to 89th in 2009. They

improved to 36th last season but fell to 51st this year, allowing

371.4 yards per game.
