In December 2008, it was announced that Morris would take over as defensive coordinator for the Buccaneers for the 2009 season after Monte Kiffin announced that he would be leaving the team to join his son, Lane Kiffin, at Tennessee. Just a month later on January 16, 2009, head coach Jon Gruden was fired by the Buccaneers and Morris was named the team's head coach. Morris had also interviewed for head coach with the Denver Broncos before being hired by Tampa Bay.
