Why some people deny to give credit to Floyd Mayweather??Are they biased?

Come on Knight! What the hell? I thought u hated floyd as much as i did!.lol!. What did Cotto do u ask? He fought the best out there. He fought Mosley( the roider lol) and beat him, he beat zab (the low blower) when he was actually good, he he fought paulie mallignaggi (when people actually thought he was good. and when he was undefeated), he fought (AND LOST TO) one of the most feared fighters in the past 30 years (Margarito). I mean come on! Cotto deserves a shot against Mayweather! BOTTOM LINE! COTTO DOESNT AVOID PEOPLE LIKE FLOYD DOES!
