The chin definitely goes to Trinidad no question!! Hearns had no chin AT ALL. How can you say Trinidad's was worse, unless you never saw Hearns fight!! Trinidad could knock out Hearns with one punch, but despite Hearns power, it would take more to KO Tito. True, Hearns could box and jab, but he was a different fighter when someone put the pressure on him (see his fights with Leonard and Hagler). You have to have more power than Tito to keep him off, and the difference between the two in physical power is close. This one goes down in classic fashion in the late rounds. I say Trinidad. Now, against Hagler, Tito would be toast!! And Leonard would box circles around Tito.
