The problem is that the Bills don't really match up that well against the Bears. If the Bills had a pure power running game I'd like our chances more, but we have quick, mobile OLmen, not maulers. It's a matchup of speed vs. speed and I like the Bears DL a hell of a lot more than the Bills OL in this matchup. The best way to beat a fast D is to wear them down and start picking up big chunks of yardage with the running game in the second half once the smallish DL tires out. I just don't think the Bills have an OL capable of doing that.
That's not to say the Bills shouldn't continue to run the ball over and over again, they should. I'd like to see them take the same approach they did with the Vikes cover 2. Stay with the run, even if it's not working and hit the short passes underneath the zone and let the WRs get some yards after the catch. They need to play it conservatively and not turn the ball over. If that means throwing to a check down WR on 3rd and long then so be it. Win a battle of field position with our ST and hope to win a low scoring game.
