I've talked to Bo several times. He isn't an easy guy to have a conversation with, but he isn't a jerk. He's closed off to people he doesn't know well, and there are people who don't understand that or deal with that well.
Not surprisingly, those are the people who come up with stories like this. There will be more stories that come out (the old softball story will be posted again soon, I'm sure), but take them with a grain of salt.
Bo is neither teddy bear nor ogre. He's a pretty unique kind of dude.
