Who fought the best version of 147 Marquez.. Pacquiao or Mayweather?
Even though Marquez was older when he fought Pacquiao in the 4th fight he was properly conditioned for the weight, whereas against Mayweather it appeared as if most of his additional body weight to reach 147 was fat. Marquez had fought Diaz at 135 the fight before he faced Mayweather at 147, in 2009 so he had to go up two divisions and he didn't appear to do it in a very effective way.
Against Pacquiao in the 4th fight, he was in the best condition he's ever been in, having hired a dedicated strength and conditioning coach, but he was three years older.
So who actually fought the best version of 147 Marquez.. Pacquiao or Mayweather?
