I will concede that the Pac12 is likely stronger top to bottom, I follow the AAC closely. There have been multiple times over the past 3-4 years where a division in the AAC has been ranked higher than a division in the Pac12 (and ACC as well).
Is the AAC better overall? I'll admit, no. Probably not. Is it close. Yes. At least, much closer than a lot of people who don't follow the AAC understand.
