For the Bills, create. It's pretty simple really. The offensive line did a great job running the ball, and they also seemed to catch defenses off guard when they did pass. Plus, Tyrod did a nice job rolling away from pressure. The OLine isn't perfect but I think they are better than given credit for.
The Bills defense has to find a way to put more pressure on opposing QBs, though. If they can figure out how to take away those quick routes that everybody copied from NE last year, the defense will be dominant again. Just need an edge rusher to replace Mario(Someone that can not only get after the QB but can also hold there own in coverage). Wouldn't hurt to have a DLineman beside Darius who can disrupt plays too. I have seen a lot of teams that are sending heat on the QB up the middle. Our guys did it 2yrs. ago. Nothing wrong with just blowing up a play from the interior.
Buffalo's opponents typically pass much more so that also makes creating a pass more important, if only from a percentages point of view. Buffalo is going to continue running a lot. That is Roman's M.O.
