Bill catches the final press conference for Saturday's main event between WBA/IBO middleweight champion Gennady Golovkin (26-0, 23 KOs) and Matthew Macklin (29-4, 20 KOs). Golovkin, 31, has knocked out his last 13 opponents.  In his spectacular HBO debut last September, he scored three knockdowns en route to a fifth-round knockout of Grzegorz Proksa.  This will be the third fight on American soil for the fan-friendly Golovkin.  Macklin, also 31, scored a first-round knockout of Joachim Alcine last September, and in March 2012 mounted a valiant effort against pound-for-pound ace Sergio Martinez, knocking him down once and going toe-to-toe with the middleweight champ before running out of steam in the 11th round.
