Enough.
Denver has not played a rushing attack like Dallas. Yes, we have three outstanding runningbacks, but the biggest component is constantly overlooked; you have not gone against an offensive line like this one. It is a big, nasty, and above all else strong unit, and if Garrett had stopped outsmarting himself he would have realized that playing to the run would be this team's best chance of winning games. Establish the run, give Romo the ability to use play-action (something he was stellar at under Parcells in 2006 and shockingly, I've seen little of since). I think he's starting to understand that now.
The only way Denver stops the run Sunday is if they stack the box, and if they do that, rest assured Romo is going to beat them over the top.
