I think we got caught up in having two separate conversations a long the way which is probably confusing a lot of people so let me clarify.
1. I don't think Nebraska is a good program right now, or even a good team in 2023. My argument was that Nebraska and NC State are pretty similar quality of teams in 2023 based on their respective F+ rankings through 2 games. It's unfair to say Colorado hasn't done anything yet, while at the same time praising ND for their win when both teams played similar quality opponents.
2. I think Nebraska is a sleeping giant as a program not based on recent results but based on the fact that it's Nebraska (they are in the same class as an OU, Bama, ND, OSU, USC, etc. historically).They are one of the most fan supported brands in the sport (similar to ND). Even when they lose they sell out 99% of their games. They are old money. And when they finally get the right people running the show they have all the peripheral-components needed to win at the highest level (money, brand, prestige, connections, fan loyalty, conference, power, etc.)
3. Nebraska recruited the 25th ranked class to NC state's 43rd ranked class last year (and the F+ formula puts quite a bit of weight on this early on in the season)
4. Nebraska's team talent ranking in 2023 is 21st to NC state's 38th which is also considered in the F+ formula early on.
5. F+ puts a lot of weight on how well a team performed vs the quality of the opponent, not just on the final score. W-L record is considered in the formula but not to the same degree as say a resume ranking like the AP Poll.
F+ is way more concerned with how well your team performed from play to play AGAINST the quality of your opponent more so than just the final score. My guess is that Nebraska despite losing more games than NC State last year did enough against the quality of their opponents to be viewed as a similar quality team to NC State even though NC State ultimately won more games.
