I think Rory shows more skills even against weaker opponents. Nate was a weight up, sure, but the way Rory ragdolled him still showed power. Rory's GnP Vs Che Mills was impressive no matter who was on the bottom position. Silva is good but Fitch will show just how good (but not that hes worthy of a title shot or better than GSP...just for the people that'll make those threads if he wins).
I'm probably the best at keeping threads on topic of all time.
