Nope, its not just about number of weight classes in any case. He would still would lack the consistency of someone like Floyd.
By my count Robinson defeated about 21 guys ranked in the top 10 at the time that he beat him. The first was in 1941 and the last in 1961.
Out of the guys Roy Jones fought the following seem to have been rated in the top ten in their respective divisions. Bernard Hopkins, Thomas...

Roy's only official loss before age 35 was a DQ in a fight he was on his way to winning by knockout, Robinson was simply bettered by the likes of...
Also, I'm not terribly impressed by this argument that Jones wins are made less impressive by the fact that he relied on his reflexes and was...

Randy Turpin and Joey Maxim
Fury and Joshua both beat Wladimir and I'm not at all convinced Ali could beat them
Ali had beaten Quarry and Bonevana by the time he faced Frazier both of whom were top contenders so I doubt ring rust would have been a massive...
Also, accusing Jones of cherry picking seems ridiculous given Robinson for whatever reason failed to face plenty of worthy opponents.
