No QB has had big runs against us or many yards. Vick had 1 30 yarder and Frye had 44 yards, but that's really been it. It doesn't skew things.
Secondly, DeShaun Foster and Carnell Williams, the two who first exposed the edges of our run defense, are not "small" backs. Westbrook, the only truly small type back we've faced, we actually handled pretty good.
