The PAC 12 is arrogant and has no self awareness. Teams such as Arizona and ASU would be better off going to the B12. The remaining B12 schools are on par with PAC teams currently. Yes, USC and Oregon have had some good teams, but the PAC as a whole is pretty much on par with the B12. Any PAC team would benefit from some central time zone games.
The reality for Arizona and ASU is that early home games have to be at night, it is just too hot during the day, so some away games at 10 am local time would bring more exposure.
I think if UCLA, USC, ASU, and AZ joined the Big 12, they would be better off.
