Ryron did not TOY with Andre.
That means Ryron's defense and escapes were better than Andre's offense and positional dominance - in other words Ryron is just better. Towards the end Andre was stalling out and super gassed. I'm sure he would've been submitted had the match lasted another 5 minutes.
Heck, the Roger v. Buchecha match from the same competition as Ryron v. Andre was an exceptional match (admittedly, in a submission only tournament).
I agree, I think that is my whole point. Not just because there was action, but because both are confident in their BJJ and it shows. They truly fought. Even though no one won, they didn't (or couldn't) win based on exploitation of the system, they had to work for it and earn it and rely solely upon their skills.
