Many of the more knowledgeable folks here have already noted it, but I think PK is mixing in a lot of different coverages for 2 reasons. First is, Clemson/Klubnik was the best passing offense/QB we've faced this year. That many new packages/looks are going to cause some errors with the DBs. However, it also caused some issues for Klubnik which was exactly the point.
Second, getting some reps in and figuring it out as well as extra film to process by the opposing OC is critical if we end up facing Oregon (which i think we probably will). That's the best passing team out there, but when Ohio State is on, they aren't too far behind. (I'm far more concerned about the OSU D than O, personally) I think we'll see more of that mix against ASU, but I think we'll focus on making them 1 dimensional and force them to pass. That will also cause some hand-wringing here as it will open some passing lanes, but worth the price imo.
