Tyson at welterweight.

[ross]

Of course he has, Tyson was a heavyweight I'm trolling really, just think it's a bit of a pointless thing to ask what if a big man weighed 150 pounds, or vice versa. The body mechanics of a heavy and a welterweight are so different, you'd end up with completely different guys.

Who has Pacquiao fought with as many first round kayos?

Who has Pacquiao faced that was undisputed champ in any weight?

Who has he faced with Tysons KO percentage?

He hasnt faced anyone of Tysons greatness.
