Juan Manual I mean... he always seemed to go down in big fights just at the wrong times. I thought may be it was a balance issue, since a lot of the KDs he suffered were in the middle of exchanges, or when he was coming to land a punch......but most of them seem pretty legit tags to the chin of course, even if he was chinny it didnt matter cause no one could ever KO him, and most of the fights he went down he got back up and battled it out like a G
He falls into the category of "easy to floor, hard to KO" fighters like Joe Louis and Felix Trinidad. If he was chinny, he wouldn't have been able to go 42 rounds against Pacquiao and he would've gotten knocked out at multiple points in his career.
Not glass, but certainly not granite. More like Larry Holmes - relatively easy to put on the canvas, hard to keep him there.
This. Anybody can get dropped regardless of how good their chin is. What matters is that Marquez always got back up
