In all fairness, and I don't like Nate that much, if he was really "seeing spots" it could possibly have been something internal. Not saying that happened, just saying I don't think there's an eye doctor on this thread and its not like its not totally out of the realm of possibility.

He did seem clearly affected by it in the round.

Or he could have read the signs and gotten the fuck out of there, I don't know. I'm willing to give a guy who's been a real fighter for a long time some benefit of the doubt. Dude has always shown toughness, Nate Campbell and the word pussy shouldn't really be used together.
