I'd be surprised if this were actually true. The Air Raid is designed to be an extremely simple offense because you get a very limited time to work with college athletes in the classroom or on the field. If we're still running a close variation of OU's offense, it should probably still be very simple and easy for guys to get.
You heard this last year from Whipple who said that he wants the passing game and the offense to dictate to the defense. This play is going to attack his portion of the field, and you should have a matchup win in spot A or B. If not, run or dump it off.
Look at when D Hop first got here or last year with Green or others. It's quite common to see Kyler after a play talking to the WR telling him what he wanted him to do on the route. D Hop was so good it really didn't matter but remember his first year here he openly said yes I'm good with Kyler getting on me I'm still learning the offense.
I would also argue we don't run the air raid. If we did we'd do way more presnap motion or jet sweep stuff. That's one of the things everyone talked about when we hired Kliff, even before we'd drafted Murray and Rosen was the guy, Kliff is going to make it easier for the QB because of all that presnap movement or jet sweep stuff it'll make it easer for the QB to read the defense, and get mismatches.
I think Kliff fairly quickly figured out that doesn't work nearly as well in the NFL and he started doing other stuff to where we're all now complaining guys don't move around enough.
