An option bases scheme out of a flexbone is never going to win championships in modern P5 football. The best teams are too fast and athletic for it to be effective. You still have to be balanced with the power running game, play action, and have WRs who can loosen up a defense. And you will never ever attract the talent to win a championship with that kind of play. It doesn't translate to the pros.
If TO kept coaching this is probably close to where we would have ended up. This offense is based on misdirection and trying to make the defense wrong. Something he was a master of. We utilize multiple types of option plays (and always have) to make the defense wrong; Read option, speed option, load option, triple option, counter option, and RPOs all out of multiple formations. Like the Nebraska of old though, we need a strong base running game for them to be effective. But with the athletic playing field having so much parity now you can't just lean on top teams with the run and wear them down like 90s teams did, which is why we have to have a balanced passing attack with competent QB, TEs, and WRs.
