Agreed.
Somewhat tangentially related, your post reminded me of the 'rebuild' narrative that's been fairly prevalent. To some degree, yes, I do think Nebraska needs a sort of ground-up approach to becoming a successful program again. However, I also think that in today's college football world, you can get a program back on track with the right coach in just one recruiting cycle. This team could easily be bowl eligible next year, and divisional contenders/winners the following year. It's absolutely achievable with the portal.
Obviously, I'm not saying that it will happen. But I don't think they're 4-5 years out from being relevant. Relevancy can come at you fast with the right people in place.
