Mayweather-Never throws in combinations.
Not an 8 piece combo, not even six consecutive punches thrown in 19 years.

RJJ- won with reflex agility and talent. He has no fundamentals. Not offensively, damn sure not defensively. His last 10 or so fights! Saying back to Glenn Johnson : horrible defense.

A lot more fighters, but those 2 for starters.

Serious Not one fighter in all of boxindom is 100% across the board.
