It has been full steam ahead for New England Patriots coach Mike Vrabel since arriving in Foxborough. He went from the podium at his introductory press conference to the office to begin assembling what many view as the deepest and most experienced coaching staff the Patriots have seen in years.

With the recent hirings of Aaron Glenn and Mike Vrabel, the NFL now has five coaches who once played for the teams they're now leading.

Two-time NFL head coach Doug Marrone, who most recently was at Boston College as a Senior Analyst for Football Strategy, is joining the Patriots' coaching staff. Marrone's specific position is TBA. His history/background w/ OL play is notable. (h/t @PatsPro_21, @JPasteris_NFL)
