Tito UD. Floyd is good but he never fought a WW like Tito. DLH couldn't outbox Tito all night and he was just as good if not a better WW than Floyd in his prime. Tito will get outboxed for some rounds but he'll come on strong late. Size has nothing to do with it but I can't pick Floyd over a WW like Tito compared to who Floyd has fought at WW.
What you're failing to mention is that all of those boxers enjoyed a size advantage over Tito, that's obviously not the case here. Tito wins a decision, but if Floyd decides to mix it up or lays on the ropes trying to counter, Tito could KO him.
By "engage", are you suggesting that Floyd would need to get involved in a slug fest in order to be "accurate"? Floyd can pinpoint without trying to slug it out.
I like PBF in this one. I think Tito would not be able to change game plan and find a way to get past PBF's defense and counters. PBF by a comfy 8-4 or so margin.
Tito style plays into Mayweather style. I can see the same game plan used on Corrales used for Tito. Mayweather by UD
