It's uncommon, sure. But really, the fans shouldn't care as long as he's out there on Sundays doing his job well, and he's not breaking any laws/harming anyone when not at work. I understand why it's weird... but I think people should be more objective about it. Let's say I'm a life long Bills fan, and I get drafted to the Raiders, do I stop being a Bills fan because I play on another team? Nah. Do I stop playing hard because I'm not on the Bills? Nah. I bet it's fairly common for players to root for other teams, but in private. So one guy gets caught in a hat, and people blow up about it? It just seems like a whole lot of something for a whole lot of nothing. Was it a bad choice, knowing how people react to these things? Possibly. But should he care? Probably not.
