I like the thought of this, but Oregon just needs to go to their video vault of Riley's years at Oregon State to get an idea of what Nebraska is going to run. Riley ran this same stuff in Corvallis, so Oregon has seen it, and has loads of tape on it.
The whole, saving game plans for such and such week, reminds me of the Callahan days of where things were so vanilla to keep the big game teams from knowing what we may run. The problem that seems to have always happened when you don't run you stuff for week 1, week 2, etc. then suddenly in week 4 want to run it, is players don't seem to execute it so well.
