Dude, as impressed as we all are with the dynamic passing attack the Bills have you'd have to be pretty naive to think they'll be any sustainable success in the future if they don't establish a competent run game soon. Honestly I'm surprised they've gotten this far. What Allen, Diggs and the offense have done this season is nothing short of remarkable. This is similar to what Baltimore did last year before they got figured out this year. Catch everyone by surprise with unconventional offense. I wouldn't expect the same results next year without a good rush attack. Doesn't have to be elite, just competent.
