Eubank Snr and Toney have the greatest chins at MW

I don't attribute his success to that much either, since most guys he faced probably was on somethign also, but of course PEDs help your chin. "Chin" isn't some mystical property we can't understand, it's muscle and bone, both of which get stronger with the help of PEDs.

Of course, his defensive skills was a huge factor, but PEDs do help.

 

Hagler and Golovkin. Eubank and Toney up there.
Middleweight has some serious chins.

 

Collins anyone?

 

I mean i can't say that doesn't make logical sense, but why then did Tommy Morrison have a terrible chin who I think it's safe to assume was juiced up beyond belief. I feel like there have been plenty of muscle bound juice heads with bad chins

 

Collins too

 

There will always be some who doesn't have as good a chin or punch as hard as their physique might suggest and some who have better chin or punch harder than their physique might suggest. But Morrisson said he would have been 190 lbs without PEDs and a 190 lbs Morrisson in all likelihood would have been chinnier.
