I'm coming around (more like accepting) to the idea of the Big 12, as long as they are able to negotiate the GOR/exit fees to where it makes it relatively easy for CU to leave in 5 years.
1. CU is going to dominate recruiting in that conference (if Utah comes they'll be right there as well),
2. CU will be the marquee team and brand to the point where I would say they'll be on FOX, ABC, ESPN, ESPN2 or FS1 for the vast majority of their games, which if we're being honest, is better for exposure in 2024-2029 than Apple TV or Amazon.
3. CU's path to the playoff is easier going through TCU, Oklahoma State and Baylor, than going through Oregon and Washington (and Utah)
4. In theory, they should/will assert themselves as the big fish in a medium, but coast to coast, pond and probably put themselves in the best position for a B1G invite.
IMO, being the standout of a mediocre group is probably better than being #2/3/4 in an above average, but not elite, group. Even if Prime gets CU to UW, Utah and Oregon's level of competitiveness in the next couple years, I just don't see significantly more upside, as it relates to the end goal of joining the B1G, in that than (hopefully) dominating the Big 12.
