i think he means arent prductive enuf. Yes it takes 85 but the qb position is a clear and present weakness that gets expoited weekly by opposing defenses. In most games, our strengths can carry the qb position but when we play really good teams, the qb position is simply too heavy of a burden for our defense and KOR unit to carry.
I think our WR's and OL are a MUCH heavier "burden" than our QB. So much so that Tom Brady would struggle at QB for us.
