The Texans ran some great screen passes to their RB or WR today, and I thought, "Gee why don't the Bills try that more often?"
Then they actually tried a screen pass to Marshawn who was immediately hammered by Houston defenders. The offensive line can't give the QB enough time to set it up, nor can they block effectively for the receiver.
QB is a problem. Coaching is a problem. But IMO the Bills can't run anything but the simplest sets due to the inexperience and ineptitude of the OL.
