I agree about too many hits and too many designed runs.
Get a decent offensive line and then the rbs can carry the ball too, and he won't be scrambling on pass plays so much either.
Bills rbs: 18 carries 41 yds 2.3 yds/c, Allen 14 carries 4.1 y/c ,3 sacks allowed. 14 carries for Allen and 2.3 per carry for the rbs is not good. A win is a win but the line is still inept at this point, I hope they get better.
