A lot has changed since 1980-1997 with regard to passing the ball. Spread offenses came on the scene in the B12 and elsewhere, the West Coast offense was tried at NU and was successful under Callahan but our defense stunk under Cosgrove, and the NFL became much more into passing the ball than relying on running backs to carry their offenses.
Nebraska has had some great passing qb's. Ferragamo, Humm, Tagge, Berringer, Ganz, Zac Taylor are a few off the top of my head. We also had some players like Churchich and Claridge before the 70's that had some excellent passing stats.
I think that Coach Riley wants to have a balanced attack. That relies on throwing the ball more than 25% of the time. I doubt that there is an NFL team now that throws the ball less than 40% of the time.
Tanner Lee I believe will be for Riley what Zac Taylor was for Callahan. Next year we will have two QB's ( 3 unless Gebbia is a rs) that can run the offense that Langsdorf has wanted to incorporate but has not been able to until now.
don't get me wrong, I hope the qb's coming in next year do great, hopefully we will have a o-line and receivers to help. Im not rooting against anything..Im just giving my historical perspective on what kind of offense works in the confines of lincoln Nebraska.
