If that trade was offered, I’d take it.
Not a chance. Rutgers is a fine academic institution. 63rd in the US News & World Reports ranking. Flagship state university of NJ. Fits academically in the B1G. Has history--was the birthplace of college football, even if it appears stillborn now.
Cincinnati is 143rd in the national rankings. Not a flagship in their own state. Not academically or culturally a fit for the conference, despite being in OH.
Maybe Cincy has more recent football relevance, but they're not B1G material.
Maybe UC is dilutive NOW but perhaps not in the future? Imagine the B12 invites say Houston and decides they need an even number of teams. Memphis? Cincy? I could envision a situation where a conference would look for a team to round things out.
Maybe.
But it might take a situation where said conference is desperate as happened last time with UL et al.
Exactly. Cincinnati won't get into P5 "by winning a lot". They might get into P5 by winning a lot in the situation where some P5 conference is desperate to add teams, and Cincinnati is the best fit of the premier G5 schools.
And even then, it depends on the conference. Let's say that Northwestern, as a private liberal arts school, decides to cancel their football program due to CTE. Do you think the B1G would rather ask Cincinnati to join, or play with only 13 teams? I'm guessing they'd look for a MUCH better fit to stay at 14, and if they couldn't get anyone, would live with 13 rather than accept Cincy.
If the whole system blows up, and let's say TX/OU go to the SEC to get to 16, and KS/ISU go to the B1G to get to 16, and suddenly the B12 is looking for Cincy (and several other teams) to come keep their conference alive? Well then Cincy won't end up in the P5, they'll end up in the G6 while the SEC/ACC/B1G/PAC will become the P4.
Cincy dilutes a conference. Nobody is salivating to add them, even if they string together a decade of good seasons. Boise State strung together a decade of good seasons, but they don't have the academics for the PAC and weren't a good fit for the B12. Hence on the field results didn't overcome everything else.
Cincy's best opportunity is a restart of truly disruptive conference realignment -- and even that doesn't guarantee that the conference they land in doesn't get decimated to the point where it's no better than where they are now.
