Three new coaches were hired in Tampa on Tuesday to help improve the Buccaneers' young and talented defensive line.

Keith Millard, the Raiders' defensive line coach from 2005-08, and Grady Stertz, who coached the position at Arizona State University, have been hired to Raheem Morris' staff. Millard will coach the lineman on pass rush, while Stertz will focus on run defense.

The Buccaneers invested their top two picks in the 2010 draft to improving their line, taking DT Gerald McCoy with the third overall pick and DT Brian Price in the second round. McCoy registered 28 tackles and three sacks in 13 games before going on I.R. due to a torn right biceps muscle. Price played in only five games before suffering season-ending hamstring and pelvis injuries.

Along with Millard and Stertz, the team added Tyrone Pettaway to the staff as a defensive quality control coach. Pettaway worked with former Bucs defensive coordinator Monte Kiffin the past two seasons, first at the University of Tennessee, then last year at USC.
