OL and LB among several concerns.
Sullivan is a solid QB but when teams force him to pass from the pocket I'm not convinced he can deliver - he's has great mobility, average arm strength, and spotty accuracy. Not sure on how fast he makes reads. People are reacting to his good play when our running game was working and he was able to use his legs but not forced to carry a game with his arm. When he's forced to do that, I don't think he can.
So getting a QB on the roster who can win a game when forced to throw is pretty critical. With strong RB room but sketchy OL I'm not sure how our running game will be, but clearly won't be as good as this year. Can we increase our passing by 100 yards / game? We'll need to.
