The Miami Dolphins fired offensive line coach Pat Flaherty in the first week of training camp, promoting analyst Dave DeGuglielmo into the role Monday.
The NFL Network’s Ian Rapoport tweeted that “Flaherty struggled to implement the new system, and it’s been an issue since the spring. It’s why DeGuglielmo was brought in.”
Offensive line is among the biggest concerns for new head coach Brian Flores, who is taking over after the team went 7-9 last season.
Flaherty, 63, has been an offensive line coach in the NFL since the 2004 season, when he joined the New York Giants under coach Tom Coughlin. He was with the Giants until 2015 before joining the San Francisco 49ers (2016) and the Jacksonville Jaguars (2017-18).
DeGuglielmo, 51, is in his third stint on Miami’s coaching staff, having served as offensive line coach from 2009-11 and in 2017. He spent last season with the Indianapolis Colts, where he was fired in January.
He got his NFL start with the Giants in 2004 and crossed paths with Flores as the offensive line coach for the New England Patriots in 2014-15.
