Firstly, there is plenty of footage of SRR, its just that most of it is past prime. But there is some footage in prime although the video quality is bad. Just off whats available i can say SRR looked better than Floyd, granted a lot of that is subjective, but his aggresiveness, movement, offensive creativity and punch accuracy blow Floyd out the water. The only thing Floyd has on him is defense. As far as stats are concerned you guys still havent explained how you make it an apples to apples comparison. The sport was structurally very different, when you fight as often as SRR did it neccessarily affects your stats as well as everything about your game.
Another element Floyd riders love to mention is how many champions he's beaten. That totally ignores belt inflation, more belts and more weight classes equals more champions. How many champions would SRR have beaten if there were the same proliferation of belts in his era?
