That was a hell of a dive by Matthysse

[John Locke]

you've obviously never been punched in the face

I don't think it was. He didn't expect Pacquiao to hit that hard, and then when he ate some of those counter right hooks early he looked very uneasy. After the 3rd knockdown he probably thought enough was enough and decided not to get up.

Plus, Matthysse got cracked hard right on the chin where he had been clocked really hard earlier in the fight. Manny was smart looking for that punch again.

Ah yes. Veteran move. That's why Manny makes the big bucks.
