You're missing the point... the UGa and Bama offenses, aren't even close to what ou will run.
Riley's is a heavy run / PA / RPO offense. They run a GT counter / counter trey type action on the OL, and let the RB's go off... but they run that same action to confuse LBs and dump the ball off to a RB or hit a WR over the top or on a crossing route...
Riley is not running pure Air Raid.... Personally, I think he's running Smashmouth with some Air Raid (or WCO) based passing fundamentals for the RPO...
Mike Leach's Air Raid is trying to get the ball to a receiver, in an open space, quickly, so the receiver can make a play with athleticism.
Riley seems to have attached that tenet on the back of "confuse the LBs with OL movement that looks like run."
Which is why he'll be gone to the NFL soon. They're going to figure out that he is doing what they really want to do... keep the same plays they've run forever and attach the ability for a WR or TE to be free in space.
If you really want to feel a little something... watch the NE Patriots offense and the Riley offense... they're really similar in what they're trying to do... hold the LB and or get a receiver into a wide open space. it's not rocket surgery, it's just beautiful play design predicated on knowing what the defense is going to key on in the run game.
WHAT?!??! Snacks has gone crazy! Nope. Watch the plays...
Some type of pull by GT... run...
Motion a slot... vacate a spot, some Some type of pull by GT, run fake, know where the 'open space' is, throw it to some small white guy you've never heard of.
Put Gronk on the line, G-counter run fake, Gronk fakes block, T blocks the guy over Gronk, Gronk is running free and you're screaming, "How do you not cover F'n Gronk?!?!" Because it was made to look like a run play and Gronk sat at the LOS looking like a doofus for 1 beat... then ran to the open space.
