DeGuglielmo, who built the Colts' offensive line into one of the league's best last season, is back in Davie as Dolphins try to rebuild OL.

DAVIE — The Dolphins, racing to rebuild an offensive line that was a liability last season, are turning to someone who led the league in that department last season.

Dave DeGuglielmo has returned to Davie as an analyst, helping offensive line coach Pat Flaherty. DeGuglielmo was the Dolphins’ offensive line coach from 2009-11.

He was on the practice field Saturday, watching linemen go through drills during rookie camp.

Last season he was the line coach at Indianapolis, which went from having one of the most porous lines in the league to one of the best. The Colts were rated No. 2 in the NFL in pass protection and No. 4 in run blocking by Football Outsiders.

But DeGuglielmo was caught in no-man’s land last season. He had been hired by incoming Colts coach Josh McDaniels, who abruptly changed his mind and decided to stay on Bill Belichick’s staff in New England. When Frank Reich was hired as the Colts’ head coach, he inherited DeGuglielmo but obviously decided to make a change as soon as the season ended. Speculation in Indianapolis was that DeGuglielmo and Reich had disagreements.

DeGuglielmo was on Giants and Patriots staffs that won Super Bowls, which helps explain his presence back in South Florida. He and Flaherty coached together on the Giants, and DeGuglielmo knew Dolphins coach Brian Flores from 2014-15, when they both were in New England.

The Dolphins are trying to incorporate versatile third-round draft pick Michael Deiter into their line along with newly signed free agent Jordan Mills, a right tackle, and Daniel Kilgore, a center who missed all but four games last season after suffering a triceps injury.
