It's honestly quite laughable that you're using this as an argument to say that Nebraska-Omaha is better than Nebraska. If we both played similar opponents and they completely outplayed that team and we lost, that'd be a valid argument, but RPI is not a concrete understanding of which team is better.
If this is a rebuilding year, what was last year? How many rebuilding years can you have?
If you'd like to bash on a team that includes SEVEN first year players who previously had no experience, that's fine. But, anyone calling for Tim Miles' head either doesn't remember where this program was before he came to Lincoln or demands national championships to form in 5 years. It's absolutely ludicrous to think that the program has regressed.
