Tried to bring in a new system that was eventually scrapped because he couldn’t teach it, couldn’t get plays in on time (Pats T-2nd in the league that season in delay of game penalties) , had no clue about stringing plays together in sequence and with purpose, screen after screen after screen, audible frustration from his starting QB, receivers running into each other because their routes were designed that way, the whole thing was a debacle. Nobody on offense could say they got better with his coaching. Funny how nobody else hired him for the role and he’s now out of the league.
