I respect the guy for his desire, and that he's gotten even this far, but the truth is it's really quite unfair.
Not for him, for the guys fighting him. This is the ultimate lose-lose situation for his opponents. If they win the fight, they get no credit, after all, they beat a guy with no freaking limbs, and maybe they get called a jerk and a bully if they really beat him down. If they lose the fight, well, you lost to a guy with no limbs, so what does that say about your fighting ability????
This reminds me of a couple years ago there was some talk about Tito Ortiz fighting Dana White, and I think there was some progress to making it happen when Tito called it off. That was the smartest thing he ever did, it was lose-lose for him. Same thing here, to a much greater degree. I wouldn't fight this Maynard guy for any amount of money, there's nothing in it for his opponents.
