Why... because Pacquiao put him down a lot?
After round 1, he was still taking bombs in the first fight.
Other than round 3, he took bombs the entire fight and didn't go down in the rematch.
Really, other than the guys on the top tier of the sport for chin (Andrade, Baldomir, Johnson, Margarito, Williams, etc.), Marquez has a pretty top notch chin.
2nd tier for sure.
