Dolphins fire O-line coach one week into camp The Miami Dolphins have fired offensive line coach Pat Flaherty and replaced him with Dave DeGuglielmo. Flaherty was hired in February shortly after Brian Flores took over as head coach, but the Dolphins' offensive line has struggled throughout the spring and summer. This move was football-based with nothing to do with an off-the-field incident, a source told ESPN. Flores has made it clear that there are no "sacred cows" in the organization and players are competing for their jobs every day. It's apparent that refers to coaches, too, after the move to let go of Flaherty. The fact that the move happened even before the preseason shows that the issues with how Flaherty was guiding the offensive line were significant. The interior of the offensive line, in particular, has been dominated by the defensive line through four days of training camp.
