flaw. every boxer has flaws, even a prime jones got knock down one time by this dude la valle. from what I know there is no footage of a prime sugar ray robinson, 46-49. I mean, flaws, physicly, he wasnt as hard of a puncher than julian jackson, but close, he wasnt as athletic or fast as roy jones jr., but close to. technicly, well sometimes he got into clinches, which could indicate his condition wasnt 100 %, sometimes he got punched, meaning he had defensive flaws.
