Mike Tyson was once p4p #1 himself. It would be an intriguing matchup to see a shrunken down Tyson trying to close the distance and take out Floyd.

As you said, there's never been anyone since who has mastered that peek a boo style with that power like Tyson.

Vinny Paz under Kevin Rooney flirted with the style and tried to use it, but to much less effect.

Hell, I was gonna bring up when Paz fought Roger Mayweather as being a lil similiar, but I remembered he was under Lou Duva at the time, who subsequently was punched in the face and dropped by Roger after the fight !
