I've wondered this to.. As powerpuncher says the judges would be a big problem, but if they made it hinge on a stoppage either way or else normal split it could work I guess. Still increases the chance a ref is compromised and stops it early though. I seem to remember Tarver making some kind of bet with Hopkins that he'd knock him out in so many rounds, but I don't know if that was legit or actually in the contract, probably not.
