It is true he has had 4 Coordinators in 4 years but this is the 2nd year in the same system. Explain to me why he has regressed with his mechanics? Throwing off his back foot, lobbing the ball and not seeing the field? We did have Torrey and Anquan, Jacoby, Pitta and Dickson for our Super Bowl run and we had good lineman too for that run- McKinney at LT, Yanda, Osemele, Birk, none of whom were mediocre lineman.
