I doubt that he went out and bought the tickets bc he just wanted to catch a game. Being that his boss also owns the local basketball team, if I had to guess it was a gift from Gayle, and he was “strongly advised” to attend with the family so he can smile and wave to the fans. It’s no different than one of those things we corporate office-work type shlobs have go to, however, I think I’d prefer his social engagement activity than the ones I have to go to.
Considering that he’s a former pro athlete, I’m going to assume that he’s a fan of sports. Also considering that he grew up in Washington state, he’s most probably not exactly a Pels fan but is enjoying going to the game and checking out the local scene. It’s just something new coaches have to do. Who knows though, he may flock up and join the murder bird gang if he ends up staying with the Saints for a long time.
