I think its jealousy of people... He is so much more talented than anyone else in the sport right now people are just looking for him to fall... same with Roy Jones Jr., but the difference is that Mayweather doesn't coast through rounds... he brings the fight to the opponent, and is very exciting to watch... unfortunately he has two things working against him... His mouth saying he is the best ever(while he very well could be), and second he has too many good opponents right now for him to face them all, and I don't think he has been picking the opponents his fans want him to... alot more people loved him when he fought Corrales and Castillo, but I ask you this did Leonard fight Hearns, Duran, and Hagler all back to back? Hell not he fought chumps too at the top, and far worse ones than Gatti, Mitchell, COrley, judah.
