Hall of Fame trainer Freddie Roach has lashed out at Floyd Mayweather Jr., for claiming to be the "best fighter of all-time." And Mayweather also stated in multiple interviews that he's even better than "Sugar" Ray Robinson (173-19-6, 108KOs) - who many experts regard as the greatest fighter to ever lace up a pair of gloves. Floyd's uncle/trainer Roger Mayweather also views Robinson as the greatest of all-time.

Roach believes Mayweather is carefully selecting his opponents, because he wants to retain his undefeated record at all costs.

"He wants to stay undefeated, because as long as he's undefeated he can say that he's better than everyone else out there. He says that he's better than Sugar Ray Robinson, because Robinson has lost fights before. Does anyone really think that? Not real fight people, no. I mean Robinson would f***ing destroy him. Let's face it, [Robinson is] a much better fighter, but the thing is he has losses on his record so Mayweather can say that he's better than these guys because he's undefeated. That zero means so much to him that he won't take a chance. He won't fight any fighter who has a pulse," Roach said.
