Let's imagine you were to run into pope who is on a long layover in newark in 5 years, he's by himself after his flight got cancelled. He's bored. You are sitting in the seat across from him and strike up a conversation. Do you think he would ignore you? Refuse to talk about BYU?
I imagine he would be engaging, gracious, and personable. I imagine he would talk about his days at BYU with fondness. He is not a different guy because he decided to focus 100% on his new gig which is at a blue blood, that he played at, and won a natty.
And it's not like he hid his allegiance to KY at all when he was here. Dude made a video wearing KY uniform and doing some weird cheer thing on the marriott center floor.
