There's no way Manny has taken enhanced drugs during his domination of fights,he's not the type.Plus with the days when Roy Jones Junior being caught taking enhanced drugs during flutuating in weights throughout his carrer i cant see Roach and Manny risking taking drugs.For me Mayweather knows how to get under his opponants skin and its working on Manny this time around,Mayweather knows it would cause upraw and he knows that the only opponant that can beat him is Manny!
