Cornhuskers!

You have to be able to throw and run to win consistantly. Back when the option became popular, there was a simple defense: tackle the ball-carrier. Now there is man-free, man-zone, spies, stunts, zone-blitzing. My point is, defenses are more complicated than that nowadays. Sure, you're gonna win some games with the option, but once you get behind...game over. It is a methodical offense that take numerous plays to grind it out and keep the other offense off the field. Now, the elite teams may not beat teams by as much, but they still win. By the way I looked at a game that Navy had all those rushing yards in in a loss to Notre Dame:
