I always thought this was a great win at the time and was so impressed with the confidence and authority Jones showed from the opening bell. Maybe it's become underrated nowadays, i'm not sure but it was treated as a top win at the time, due to Toney being #2 pfp. Jones wasn't rated as highly before the fight as is often claimed (he was #7 pfp in Ring) - although there's no doubt he was rated as the heir apparent to the #1 slot.
I found it a startlingly dominant performance, over another great fighter. Nearly a shutout by my recollection. Great win for RJJ. I would have it as one of his best wins, Toney was a top tier opponent. Not sure I buy the whole weight thing, and given the styles matchup it seems likely that the outcome would be the same, regardless. I do think it would have been interesting to see them matchup at LHW, or even Cruiserweight.
If only Toney would have been in shape, it would have been a different fight. At least a competitive fight. I do not think anybody beats a prime and tip top shape Toney easy
