Early this week... day or two ago... Joel Klatt was on The Herd... talking about Ohio State.
Ohio State's OC is.... Kevin Wilson (got the name right)?... who was OU's OC when OU played Urban Meyer's Florida team (with Tebow) that beat OU for the championship.
Klatt said (even mentioning that with Beck gone from last year) Ohio State's offense is run in (what Klatt called) layers.
He went on and on about how the offensive scheme is designed for routes, open receivers, done depending on the pre-snap situation. And practiced to the point the team knows what to do as they line up because of what he termed "layers" as opposed to more simple 'scheme' concepts. The idea is that the QB and offense line up and can see which layer to go to... and the options within that layer.
As I take it... they now know the layer to work from and the QB can check down on the pre-snap read to get it just right. But all the players know where they are within that layer. Next series or down-and-distance, they may shift to another layer.
If my comments here sound odd or like I have no idea what I'm talking about, that would be true. Maybe all offensive schemes are in layers. But Klatt is of the opinion Ohio State has the best offense going and attributed it to a former OU OC.
