Name me some cast iron chins that have been dropped?

[BigMacFoster]

John ruiz against Tua

Mr Ruiz got more than dropped

PAC, MAB,

Pacquiao and Barrera have absolutely no business being in such discussions as neither have particularly good chins

[Dynamite Kid]

Julio Cesar Chavez. I was shocked to see Randall put him on his backside.

[Spartacus Sully]

i would go with John L Sullivan and Jim Jeffries as far as chins as hard as they come. not sure between the two though i think perhaps id have to give to Sullivan though as the GCOAT

errr didn read the thread correctly....id have to go with jeffries vs jhonson and dempsey vs tunney

they had both gotten knocked out of the ring

[Joe2608]

Reggie Johnson dropped James Toney at Middleweight.

[mrboxer]

ali had a real good chin,took a lot of punishment for it,george foreman,got hit with a lot of shots that other fighters would of needed smelling salts to awaken,ali has hit the canvas before and foreman got kayoed once but their chins are still made of granite,there are many more out their but these two ring a bell

[John Ruiz.Jr]

John ruiz against Tua
