My high school lo those many years ago ran an offense they called the Notre Dame Box, but my father always said it was really just a Winged-T. AU's offense reminds me of that a great deal. I would argue that you almost need to abandon any keys or reads and simply hold your spot on the DL, regardless of what the OL does. AU is particularly good at disguising their plays by doing unorthodox things with their OL.
Combine this with very little time to adjust and you get outflanked a lot if you are trying to do too much on D.
My real concern about what is going on is really with the officials. If the stated purpose of an HUNH offense is to gas a defense full of 18-23 year old men in prime physical condition so that they start to ignore their fundamentals, get out of position, and make bad decisions, what in the world does it do to the officials? And if it cuts down on defensive adjustment time does it not also cut down on the time the officials have to do their checks for illegal formations, eligible receivers, false starts, and such? And I pity the poor umpire, who many times barely gets away from the LOS before the ball is snapped, and really has not a prayer of getting into position to call anything but the most blatant of holding penalties - assuming of course that there were holding penalties to call. There may be even more misdirection here than meets the eye.
I hope that Alabama decides to include a no-huddle package (not necessarily hurry-up) in their offense next year designed to hamper defensive substitutions. I would love to see what our OL and RBs could do against a DL that was good and gassed about midway through the 3rd quarter.
