Who the hell says John Ruiz has a better chin than Wlad?!?! Who says Valuev has a better chin

NEW RULE: You can't say someone has a good chin when its never stood up to anyone with power.

Ruiz LOSS KO 1 to David Tua - proven heavyweight power puncher (only one he ever fought, lest you count the WBA title holder)

Nicolay Valuev has NEVER fought a proven heavyweight power puncher but I saw Monte Barrett rock him pretty good as well as Taras Bidenko (not big punchers).

I'm not saying Wlad's chin is granite...I'm saying comparing Wlad's chin to Valuev's or Ruiz's is not apples to apples given who they've fought.
