Patriots offensive coordinator Josh McDaniels said: "Josh has given us consistent play. He's played at both guard spots this year, so he's had to be in tandem with a lot of different people, certainly the center, David Andrews, but also both tackles, or all the tackle combinations that he's played alongside. He's an intelligent guy. He's tough. He plays very hard, and he always gives us everything he has, so he's a guy who's been in our system, he's learned how to play in our offense, and he's a valuable piece to what we do. We count on him to provide veteran leadership and help the communication process up front along with the other guys. And he's done a very good job of [being] accountable to his job, accountable to his preparation every week and comes out and plays a full 60 minutes every week."
