The key to stopping ASU isn't hard to determine. It's physical, but very straight forward
Defensively: Don't send a blitz at Osweiller 3 downs out of 4. Contain him behind the line and make him run laterally. His comfort zone is the pocket, so out of it his capacity is greatly diminished. His height is an asset and a weakness. He can see over everyone on the field but those long legs are tailor made for BSU's defense. Jam ASU's receivers at the line- throw off the timing. This will be especially effective against the sideline routes.
Offensively: CONTROL THE BALL and the clock. Pound ASU in the center then hit the edges with swing passes after ASU has to honor the run. The long ball will fall into place on it's own. Isolate Burfict! Put someone on him every down. Whether he's near the ball carrier or not? I would suggest a TE crack down on him. Let him know he won't be the determining factor in the game. We used that startegy a lot in HS years ago against defensive players that were a problem.
Special Teams: Two words- HIT and HUSTLE! Nuff said there. (A rugy style punt would be a nice weapon to use as well) Oh yeah? Almost forgot. Hitting a a field goal or two would be really nice!
