All those punches he ate from Berto, snapping his back, left and right, only wobbling momentarily a couple of times, I think the damage will show in his next fight. I think a lot of people will disagree with me but this fight will end up taking a lot out of Guerrero. It was his "night" but notice this happens a lot, a fighter goes through a war and wins but then in his next fight he's not the same fighter.
If Guerrero has more fights left in him, then good for him, I actually liked his performance on Saturday and think he should fight like that more often. He has a really good chin, he showed it. Berto knocked down Ortiz twice with some of those punches, but Guerrero took them.
I think Pacquiao may UD him. I don't think Guerrero gets knocked out like counted out. Worst that happens to him is that he gets stopped by the ref on cuts, bruises, or he gets badly hurt and the ref or his corner stops the fight while Guerrero is standing wobbly on his legs. I don't see Guerrero actually going "down" though. Very good chin, Berto threw some jaw breaking uppercuts, some brutal punches there and although they got Guerrero's attention, he kept coming.
