Pacquiao-Marquez III flipped the familiar one-two punch atop boxing's pound-for-pound list—with an impressive combo following right behind
1 Floyd Mayweather
A one-sided whipping of Victor Ortiz in September, coupled with Pacquiao's uneven effort against Marquez, moves the inimitable Mayweather back to the top spot.
2 Manny Pacquiao
The wins go on, but against Marquez, Pac Man wasn't the all-devouring champ he has been. Still, the Filipino southpaw remains the world's hardest-punching congressman.
3 Sergio Martinez
A powerful, athletic southpaw, the 160-pound king has offered to come down to 150 and fight for (relative) peanuts for a shot at Pacquiao or Mayweather, with no success.
4 Nonito Donaire
The dynamic switch-hitting 28-year-old bantamweight champ, who's riding a 26-bout winning streak, will seek bigger challenges in higher weight classes next year.
5 Wladimir Klitschko
