So, Is Floyd Mayweather Scared?Barry Petchesky7/14/10 12:45pmFiled to: BoxingFloyd Mayweather Jr.Manny PacquiaoBert Sugar31EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkWhat other possible explanation could there be for his unwillingness to fight Manny Pacquiao, even after Pacquiao has agreed to the stricter-than-necessary drug testing that derailed a potential March bout?The initial dispute was over the proximity of blood testing to the actual fight. Mayweather, floating those "Pacquiao is doping" rumors, wanted blood to be drawn within 30 days of the match. Pacquiao said no thanks, he'd stick to the rules as they are now. At the time I figured it was mind games, just Mayweather looking to gain a psychological edge. Then the fight never happened.
