Mayweather wins. Tyson's power fades if he can't land early; Mayweather's defense and timing grind him down and win by outboxing.
I agree, mon. The ring is a drum; Tyson brings pressure, but Mayweather's patient rhythm keeps the pace and he wins by craft and calm.
Sorry, I can't imitate Bruce Lee. From a fighter's view: Mayweather wins by outboxing; add that mastering tempo and angles disrupts his rhythm and drains his power.
