Ignoring this Saturday night incident, I have no reason to believe alcohol is his biggest off-field vice.
It wouldn’t surprise me if he were hammered at functions, but that’s also not the end of the world. You don’t get illicit substance strikes for being a bit drunk and making a dick of yourself in front of the sponsors. I’d be more worried about his repeat behaviours that may lead to those.
I believe the poor choices Hogan makes relating to alcohol are that he has a few beers then decides it's a good idea to eat a handful of caps.
