Nebraska is unique. TO fully took advantage of the unique attributes of Nebraska with his system. A WCO could work if all the stars aligned perfectly, but you're swimming upstream trying to implement that type of offense. It doesn't fit in well with TO's entire philosophy.
Nebraska football as we know it began when Bob Devaney rescued Nebraska from the "three yards and a cloud of dust" offense of Bill Jennings. Devaney's first play as coach in 1962 was a forward pass, and Memorial Stadium gave it a standing ovation.
TO helped Bob Devaney win Nebraska's first two national championships by introducing MORE passing and indeed more complicated offensive sets to the previously conservative run-heavy scheme.
As HC, it took Tom a full nine seasons before he settled into the power option game we remember. It took him 20 years and a perfect set of recruits on both offense and defense to create the 1990s powerhouses we remember -- and to shut up Tom's critics.
Tom Osborne is on record as saying that the run-happy offense he once perfected probably wouldn't work in today's game. So there's that.
It is increasingly hard to recruit top tier players for a scheme that doesn't prepare them for the NFL.
Who is the dream candidate you'd choose to replace Riley? Have you vetted his run/pass ratio? If Riley is pass-happy, then so is everyone in college football.
And let me get this straight: you celebrate the appearance of Andy Janovich and cheer the revival of the fullback trap, but withhold all credit for the coach who pulled it out of the mothballs and continues to run it?
I've asked this on two other threads and gotten no answer:
Assuming he was available (he wasn't) would you have grabbed Paul Johnson and his run-first offense for Nebraska in a heartbeat?
Would it change your mind that Johnson is currently 2 - 4 at Georgia Tech, with worse losing margins than Mike Riley at Nebraska?
