I'm not sure if this has been ever discussed, but why not start a fantasy boxing league here on ESB. I'm in a fantasy boxing league on another website and it's where you predict outcomes of a fight and at the end if you finish first you win some cash and stuff like that.
I didn't know, it's not like I see it anywhere on the front page and sign up for it....if it's here in the forums it's not doing much good.
