He's kinda falling apart as a HC, but I've always liked Rex. He's funny, enthusiastic and he approaches the game the way it's supposed to be approached...like a game.
I don't get why he catches so much hate. I understand why fans of rival teams might get sick of him, but that's it. I'm pretty sure lots of people just hate on him because that's the trend, and they're not really sure why.
His players love him. He's entertaining. And he's just an intriguing figure.
