Matty Mac has been a UT super fan for quite a while. I remember him doing a bit with Will Ferrel when Texas played USC in the National Championship. Every school has one.
I have no doubt he is a legit fan of the team (like Cam Pritchett is of ours) but I’m also sure his agent/publicist has had a hand in making sure he’s at all the big games (and on film being there).
