McMurphy said that one P5 athletic director told him that if any part of the football season gets canceled, "we are f*****". He did not say who said that.

A couple are in the PAC-12. I would think that outside of Missouri, the SEC is OK. Although I don't know for certain, there are other programs that just can't keep up with the Jonses without football.
