The last major piece of Buffalo Bills coach Doug Marrone's staff has been added.
The Bills today announced they've hired offensive-line coach Pat Morris.
He's a 15-year NFL coaching veteran who has worked for four teams, most recently the Tampa Bay Buccaneers in 2011. Morris, out of football last season, also has been an O-line coach for the San Francisco 49ers, Detroit Lions and Minnesota Vikings.
Morris began his coaching career as a graduate assistant at USC and spent several years as an O-line coach with major programs, including USC, Michigan State and Stanford.
