Exactly. Fucking exactly.

I can't even imagine how that might be considered unsportsmanlike but then I haven't shaved my neck in years

This is the definition of unsportsmanlike.

The punch was completly legal or course. But sportmanship doesn't have to do with rules. It's about the nature of sport and the spirit of competition. I don't feel any sypathy for the guy with the knocked off block, but I'd never be a fan of a fighter who wants to win like that.

Or more aptly, if you're going to touch gloves after the bell, do it at arm's length. It may be a cheap shot, but from the vid it looks like he caught him with a hook, which means this guy is way too close.

His left hand was up in the air for a high five.

In the words of the Fight Night 3 announcers... "Its the ones you don't see coming that always hurt the most."

Yeah, it's almost like he was completely incapable of defending himself when the guy hit him or something! What a pussy!
