Mundine started well in his career, but like RJJ he is more of an athlete than a boxer. once he started to age and cut weight to go down divisions,he couldn't hang. And the level of his competition while already got worse.
Also everytime he vs'd great/elite competition Ottke KO'd him (great day in Aus) and outpointed by Kessler.
He got a gift against Geale, but easily outpointing Green but never hurting him.
