So we're only counting wins under Rickson's rules, or if they ended in a submission?
I'm talking competitions/fights that don't count pinning someones shoulders on the ground for a second a win. Something that somewhat resembles actual combat. Do you really consider Ron Tripp a better grappler than Rickson? If Tripp had taken Rickson down, dominated him and controlled him positionally on the ground, but had not submitted him, I would consider it a win for Tripp. But that didn't happen.
Edit: Basically what I am saying is that how do you know that if it hadn't been stopped after the pin, that Rickson wouldnt have just recovered guard and arm barred him (which is probably what would've happened)? Tripp needed to show that he could do what he did, and then avoided rickson's attacks on the ground to be considered a real win IMO. But yes, it was a win under those rules, which are unrealistic in actual fighting.
