Its not luck, Roy would go out and dominated anyone he was in against in his prime, he wouldn't let them compete with him. He would dishearten them in the first one or two rounds by either surviving their mindless wirlwind assault, or he would come forwad and hit them with anything he wanted, but he used to set up shots, it wasn't his speed that made him special, it was his ability to use a punch one moment to set something up the next. Every punch he landed or didn't land had a purpose in his prime. Now he was just potshotting like an ineffective Bernad Hopkins or Floyd Mayweather because he doesn't have their elusiveness of the ropes. I shouldn't even say that because he didn't get hit to the head that much, but where Floyd Mayweather and Bernad would have either fought off the ropes or clinched Calzaghe, Roy would just take the punches off his arms. I was mad also that he wasn't punching when Calzaghe dropped his hands, he legitimately threw punches while Joe had his hands down, but what made me the maddest was two things
1) When Roy backed up Calzaghe, who seemed to need breaks or something during the fight, He never threw a damn thing except that right cross, and it did land, but he made it so obvious what he was doing that Calzaghe could time it, instead of forcing Joe to react to his speed.
2) Roy almost never punched off the ropes, Calzaghe wasn't really able to hit him to the head with anything of any consequence when Jones was the ropes, yet he didn't throw his fucking punches. The few times he did he countered Calzaghe well with uppercuts.

Ali punched off the ropes, Robinson had the chin.
