You can put on a video of select highlights of Calzaghe in his prime, and make the exact opposite claim. The fact is, when the fight finally came off, Calzaghe outclassed him. End of story. If Roy's legacy is based so much on "looks" and speculation, that's not a good thing.
Anyone who has seen Roy in his prime (earlier years not just necessarily at light heavy) would have seen that it was indeed a shell of his former self in there this past weekend. It is sad, especially with Jones, considering how much he used to fight like a superman and how ordinary he is now. If you analyze close enough, a sign of him slowing down was a bit present even when he had fought Ruiz imo, but it was masked by the fact that he was fighting at a much higher weight and fighting a much slower opponent. For example, one could justify that naturally he would be a bit more flat footed at heavyweight because of the extra weight. The first thing that Jones' lost was his legs. Next, his reflexes. Last, his hand speed.
Yes, the highlights are awesome, but lets not forget the guy could just be so negative for long stretches in the ring. I mean the guy went 12 with Telasco and Gonzalez, and he went long rounds with plenty of guys who had no business going rounds with him.
