I dunno man, you have a good argument, but Spencer is quick man. The speed he was throwing combos (punches, kicks, knees together) against Stout was impressive. Melvin's hands are a blur when he throws, but Spencer just seems to move faster overall to me...comes at you from different angles of attack.
Melvin throws fast, but doesn't move fast is what im trying to articulate. Joe daddy dropped him with a fairly lazy jab. Spencer would have dodged that.
Demian Maia may be the Fred Astaire of jiu-jitsu, but itís too bad Silva is the Gene Kelly of kicking everyoneís ass.
