After Sergio Martinez knocked out Paul Williams with a single punch to keep his world middleweight title, promoter Lou DiBella suggested Manny Pacquiao would be too scared to step up one more division to face the Argentinian boxer.
That’s a bit unfair.
There is no reason for Pacquiao to step up to middleweight (unless he wants to). If he keeps stepping up, he’ll eventually run into somebody who is simply too strong for him.
Anyway, the only fight for Pacman is Floyd Mayweather.
