Your probably right though I think SRR quickness would be much closer than Roy was used to. That would make the other variables come into play. Who can establish a good jab? Who was willing to take chances to lead? That could work either way. I was a fan of Roy but I wish we had a little more film of Robinson at his peak. There's the possibility this fight is a stinker as well.
Sometime in the middle rounds in a competitive match Sugar Ray will hit Roy with a hook and he'll do a little jig , then he's put to sleep with a combo. Jones got by on reflexes and speed not sound technique. Add a weak chin and you ain't beating the greatest pound for pound fighter with just those
