I listened to the full segment on that Podcast. The guy said he has a source who told him that Rocky feels that he has taken SDSU to the highest level possible in the Mountain West and is looking to either retire or take a nice paying DC role at a P5 program. He referenced Junior Seau a long time ago saying that he was going to retire but then wound up signing with the Patriots a couple weeks later
They did talk about SU for a little bit and said that even though they feel SU is a middle of the pack ACC program at best, SU can still offer more to Rocky than SDSU can
