I know the staff has broke this down already, but I saw the segment on Sportscenter on what the Ducks will do to try and slow down the Buckeye Offense.  They play a 3-4 with 2 Giant Sequoias playing DE/DT, whatever they are called in a 3-4.  Anyways, Tebow/Herbie said they will play an inside alignment on the tackles, much like Bama did on Zekes 85 yarder.  They will do this to force Cardale to keep on the zone read, since the middle will be clogged. 

They must have not read the breakdown of Zekes 85 yarder on 11W, because the Buckeyes will adjust by the tackles blocking down, pulling the guard, and Spencer will fire in like a Tomahawk missle, taking out the entire LB corps at once.

Bold Prediction (well, maybe not too bold if Oregon plays the zone read this way)-Zeke will house a 50+ yarder.
