He wasn't very feared by '03 IMO. He was just a name. Same as Chavez was when Tszyu beat him, and Duran was when Joppy beat him, and Leonard was when Camacho beat him, and Ali was when Holmes beat him, and on and on and on.... None of those are great wins though.
ok, got you i suppose the fight wouldnt mean much but tyson would still have the big punch and alot of weight on RJJ and Tyson is more well known than Ruiz so theyr would have been more coverage (not taht has to do with the win)
