Definitely overachiever, beat some guys he wouldn’t be favoured over in fantasy matchups, I doubt he’d be favoured over Sanders and definitely wouldn’t be favoured over Lewis.
Slightly above average fighter. Maybe a notch above someone like Lyle/Ruddock/Whyte types, but only by a smidgen. A decent all around boxer with decent fundamentals, a good jab, pretty good power, and brave. He gave us a few really good fights, but he also gave us some stinkers, along with some pretty average/forgettable ones. He was a bit all over the place with his results. He could manage to become champ in some eras, but would fail to become champ in other eras. In other words, he did a little more than what was expected of him. Fringe top 40-50 guy. His biggest issues were his lapses in defense and lacking imagination/variety when plan A didn't work.
I think he was an underachiever to be honest, I mean the guy knocks out Lennox Lewis, but loses to John Ruiz.
This. Rahman had a good jab, excellent power, and he was fearless. When he was in shape and motivated he could be a problem for anybody, but unfortunately his conditioning and motivation were inconsistent, so I also think he underachieved considering the tools he had.
