These zone reads are what make me cringe. They are so "all or nothing"
IMO, you hit the nail on the head with just that. I've always preferred the old Big Ten offensive style (3 yards and a cloud of dust). Only I would sprinkle in more play action. When people complain about only picking up 3 yards on a run play, I always tell them, "You know, if you are guaranteed to gain 3 yards on every single play, you would be unstoppable. You have 4 plays to gain 10 or more yards." Of course that's not reality, but we've done it to plenty of people this year, and a few teams have done it to us: when a defense gets consistently run on, and can't make stops on 3rd down despite its best effort, it is demoralizing. It's a whole additional part of the game that doesn't necessarily show up on the stat sheet.
That was Nebraska's M.O. for years until Callahan got here: run the ball, be the more physical team, and wear down the opposing defense. By the 4th quarter you end up gashing the defense for big gains because they are mentally and physically exhausted.
But to do that, you have to have a physical rushing attack. At times, we have it, and other times, we don't. Our offensive line was probably the best run blocking line we have had in over a decade, and it's something that really went under the radar. We need to use that to our advantage during the bowl game, because in passing situations, our OT's really are the weakness of the offense, and are horrible in pass protection.
