Ortiz has shown that he can absorb more punishment. I'm not sure if Khan would've dealt with Lopez's punches as well as Ortiz did.
Well, Khan dealt with Maidana's punches a hell of a lot better then Ortiz did. At 140, I think Khan has a better chin. I'd like to see Khan at 147 before I make a decision on who has a better chin overall.
Khan's heart and will to win>>>>>>>>>>>>>>>>>Ortiz. which is all that matters.
Khan was out on his feet against maidana for 3 rounds and never quit. Ortiz would have..... oh wait that actually happened LOL.
Some of those blows Ortiz received by Lopez would have knocked Khan down.
Broken jaw != weak chin
Yet Khan was able (just about) to stay on his feet against Maidana who dropped Ortiz twice and made him quit
Khan even though has an average chin his heart Anorak said is much greater than Ortiz's. Even when Khan is in trouble he still has a will to win, but Ortiz however seems to just crumble a bit, except against Berto in which he was pretty much dominating him anyway's so the knock downs didn't affect him too much, but when a fight like this one is which its back and forth action Ortiz starts to lose mentally. This was present against Maidana and to some extent against Peterson during the latter rounds.
