La Motta, Hagler had pretty good chins. Heavyweights, Chuvallo, McCall and honorable mention Rocky Sekorski
Erratic Behavior's right, read the book and you'll get it. In LaMotta's own words "They made me look like a pussycat"
Haven't heard La Motta speak in a few years but the last time I did he was pretty damn old and I did not detect a trace of him showing the effects of all those shots he took. Strong chin, and stronger brain.
James Toney has the best chin ive ever seen.... Mayorga in his day... wayne mcsomething lol... i know his name just not how to spell it. i dont know enough of jake outside raging bull to say... just from what ive seen... Hagler Mayorga Baldo James toney hopkins seems to have a good one Oscar de la hoya (very underated) just to name a few but ya id have to go with James Toney
Gatti? i dont think he had that great of chin... he was hurt often. his heart is what kept him in it.
