I could see McCallum stopping Tito in a fight that might be easier than most people think. McCallum was a class above Tito.
I actually see this as a bit of a mismatch. McCallum soundly beats him into a TKO, and around the tenth as others have said sounds about right, kinda like he did McCrory. It's not to say Trinidad was a bad fighter or THAT much less than McCallum (though he must certainly be ranked below him); it's a styles thing. McCallum would absolutely eat him alive. Counter him to death, and Tito would just keep walking in for more.
Agree. McCallum has an ATG chin and is much the better technician, so it's hard to see a way for Tito to win.
McCallum by easy KO in about 10 rounds after softening up Trinidad with his usual body attack. Trinidad couldn't KO nor outbox McCallum
