Wouldn't it piss you off if you were paying him millions of dollars and he decided to party, instead of taking football seriously? It's their own fault, because they were stupid enough to draft him!
No, I would not be bothered by a guy partying on his OFF TIME, as long as he didn't show up for work hung over. You don't have to be in work mode 24/7/365... I CAN'T... NO FCCKING WAY. I need "party time" .... NEED! I wouldn't begrudge a guy that.
