A one back 'backfield' (excluding the QB of course) is NOT an effective run formation in general and will not produce the kind of powerful run 'identity' that Nebraska needs to re-establish itself with in the future. You can keep one back in the backfrield primarily as a safety blocker and relief valve type receiver in the passing game but those "h backs" and other names for slot receivers and other unorthodox RBs positioning and alighments are not the same as a second true RB behind the QB within the pocket really. You need multiple ball carriers in position to attack into the line of scrimmage and to block for each other as well as to fake to in the course of both run and pass plays.
Scat backs just don't pose the threat to push the pile and or block the LBs and safeties so the run game is more of a complement to the pass game than in integral or essential element of the offense. The run game becomes the side dish versus the main course so to speak. You need to be gaining 250 yard on the ground and 250 in the air to have a powerful and effective and balanced attack. If you slip, it needs to be in the air and not in the run yardage really. I've always felt run yards count double of pass yards in terms of points and in some kind of weighted comparison. That is, a team that gains 500 yards passing will not be as dominant as a team that runs for 500 yards. Points averaged will be significantly higher for the running oriented teams and winning margin as well. I have not seen reall stats but I believe the numbers will really bear this out.
A team that runs for 500 yards per game will outscore a team that throws for 500 per game. I believe a team that runs for 400 and throws for 100 would slightly outscore the 500 run ypg. And 300 rush and 200 pass would be slightly higher than the 400/100 and 500/0. But I believe the numbers would turn the other way below 300 and by time you get to 200 rush and 300 pass, the scoring will have fallen off dramatically. 100 run and 400 pass will see a win / loss ratio dropping into the 65% or so. Again, I can't cite hard stats but I am confident if the research was done, it would be borne out.
We appear to be building a team that will be in the 175 run and 275 yard pass ratio. This may not produce much better than a 65% win / loss percentage and that will be 'ify' in the years with tough schedules.
I will prefer it if we find 275 run and 225 passing or more. That will get us 11 wins a year and we'll all be much happier.
