Lets be real here and talk heavyweights...when's the last time you guys saw a 5 round heavyweight bout? The truth is even 3 round fights at HW don't come around more often than definitive finishes. Cain showed he was the better man, and JDS showed he had the heart of a champion and weathered the storm.
It's one thing to see a guy get a beating put on him, it's another thing to see the guy get knocked out in the first round. JDS played it right and was able to survive after Cain knocked him down in the first, Cain could not do the same and was finished. I think JDS kept more of his pride.
