What are the chances that arg has been cheating his whole career?

Mosley is much older and yet had a much greater chin than any of these other guys.

Let's not forget that Shane Mosley has a history of being a drugs cheat and perhaps Margarito and his camp thought that they should even the playing field a little.

No. His chin was certainly better than Cintron and Johnson's, but about on par with Miguel Cotto in terms of damage retention (i.e. how much pain they feel from punches). And Cotto has much more endurance (i.e. he was willing to stay up for longer and take more pain), yet still went to the canvas many times - in the Margarito fight! Before that, Cotto had never taken a down, nor had he ever begun to seriously bleed.

That makes perfect sense. Someone used to take illegal drugs about 10 years ago, so we'll just strap on some rocks in our gloves to even out the playing field! Forget for a moment that Mosley hadn't used the drugs for 7 or 8 years and about 25 fights, including against Miguel Cotto (who was meant to be a much harder opponent). It still makes perfect sense, doesn't it?

P.S. That wasn't meant to be mean or nasty, just to make a little funny joke. I have a feeling you were joking too ...
