I'm sure people would focus on the sequence of events if he missed. Hell, they are thinking about it in the win, so that is a pretty rhetorical question if you asked me.
In all honesty, after talking about this all day, I think whoever ran on/off the field when they shouldn't have may have saved the Cowboys from themselves.
After all, I have a hard time believing fans or the media would be discussing this as much if this happened with Tom Brady and Bill Belichick. It would have been more like Tom and Bill doing what they do.
