Let's be clear, I wasn't comparing the P12 to the B12 top to bottom. My point was that taking the best teams from the P12 and adding them to the B12 makes the B12 a clear Power conference. Without them (and discounting CU because well, we've sucked in the last couple of decades) looks meh...ok.
So what teams are consistently good and legitimate P5 football schools? TCU is solid right now, but history says it will likely return to the mean. Okie Light is probably one of their better teams and has been consistently good. The others have had some good years here and there, but they just aren't awe-inspiring. So yeah, it's a power conference, but in my view, a weak one. Adding UW, UO and Utah makes the conference formidable.
Regardless, it's CU's best option. It is what it is.
