HBO Arm Length

[marbleheadmaui]

I completely disagree. What the HBO "arm-legth" measure measures is who has the edge punching the other guy's shoulder. WHO CARES! The single most important punch in controlling distance (perhaps the single most important step to winning a fight) is the jab to the head. So the distance across the shoulder (ignored by arm length) matters a great deal. REACH is the far better measure in demonstrating that.

Of course the best might well be the distance from a closed fist to the side of one's face when facing forward.

The other issue I have with it is, as a history buff, I have no way to compare "arm-length" of a current fighter with fighters of the past. But that is a seconday point.
