joshua at this moment / even if he is still a novice looks a more complete fighter than rahman 6.6 to 6.2 and with an abilty to control from the outside until he lands something big joshua has the advantage in speed and boxing ability and size rachman could land a big one no doubt / but he was also susceptable to punches all the time not having much of a defense or any leg speed. his big right was telegraphed . hindsight on joshuas career is needed to fully asses the match up /as we know everything there is to know about rachman as opposed to joshua.
Actually Rahman at his best was no joke and a painful night on the town for anybody. At his best I think he beats Joshua as he is now. Rahman's problem is that he couldn't stay in shape or motivated and alternated great performances with shoddy outings. But we haven't seen the best AJ yet, I think.
At this point, given that there are questions about Joshua's chin, Rahman might win. He had a knack for KOing British fighters with suspect chins after all! But Rahman's chin is PROVEN china, so I lean toward's Joshua, 60/40. This said, if Joshua's mandible is as fragile as some assert, this could be a case of whoever lands first winning.
In the Sanders fight he took some hellacious shots and hung in there until Sanders gassed. I'd say it's not great, but not awful either. It depended on how determined he was to win the fight.
