Until he was stopped he did all right. But if memory serves, I had Darius well ahead in both. Roy's true asset was his otherworldly reflexes, truly amazing, and stifled many a very good fighter. That, combined with his confidence and composure in the ring, made a deadly combo. It seemed that the fight game was "slowed down" for him, that he almost saw things before they happened. I think his unfortunate decision to carry on has lowered his true and deserved ranking as an ATG.
Yeah, you have a point here. But still, I think fighting outclassed opponents isn“t really proving that he could do it against stylistic similar but class-wise better opponents. Know what I mean? Going by potential, you are completely right. Jones and DM are in different leagues here.
