I think we've established how atrocious the New England Patriots offensive line performed in 2015. Almost every single player to suit up on the line was hurt for some extended period of time, and the team had to rely on a series of young, inexperienced, and hurt players to protect the best player in the NFL.
Tackles Sebastian Vollmer and Marcus Cannon were awful. Guard Shaq Mason was a rookie coming out of a triple option offense that rarely threw the ball, while Josh Kline and Tre Jackson battled serious injuries.
