Good analysis, jogger. That having been said, I would like to make a point that I haven't seen made in this thread much. Remember, we're talking about the -best- of each of these fighters in the world. If the world heavyweight boxing champion lands a head shot on any of these people, it's game over...their opponent is going down and they're not getting back up. World-class boxers are also masters at -avoiding- getting hit, a skill of theirs that is highly underrated. The martial artists aren't going be able to take the boxer to ground if they're never able to lay a hand or foot on him. I'm not saying that the boxer would necessarily be the winner, but I think he'd do a lot better than many people in this thread would give him credit for. The power of a punch thrown by a top-class heavyweight boxer is overwhelming. There's a good reason they're legally required to register their hands as lethal weapons in most states. They need to avoid being taken to ground by the martial artists (at least if that martial artist is still conscious when he hits the ground after the boxer lands his blow) at all costs, but other than that I see no huge disadvantage for them. It's not as easy as you think to land a blow on a heavyweight champion who doesn't want to be hit.
