Buffalo Bills coach Doug Marrone made another addition to his new staff Saturday, naming Pat Morris as the team’s offensive line coach.

Morris has 15 years of NFL experience, the most of any of the 17 assistants hired by Marrone since he took over earlier this month.

Morris was out of football in 2012. He most recently was the offensive line coach for the Tampa Bay Buccaneers in 2011. The Bucs finished that season ranked 30th in the NFL in rushing.

Prior to his season in Tampa Bay, Morris coached the offensive line in Minnesota (2006-10), Detroit (2004-05) and San Francisco (1999-2003).

Morris has guided an offensive line that paved the way for a top-10 rushing offense nine times in his 15-year NFL career, including three years as the league’s best (1998, 1999 and 2007). Morris’ offensive lines also blocked for a 1,000-yard rusher 11 times in his 15 seasons in the NFL.

Prior to coming to the NFL, Morris had 21 years of experience in collegiate coaching. He played at Southern California from 1972 to ’75.
