I agree that strength is a factor, but as for equalizing it, I'm not so sure. Look at UFC 7 with Ruas and Varleans. Paul was taller and appeared to be stornger than Ruas, but Ruas' tech. was much more superior than Pauls.
What is the secret to Rickson Gracies success in the ring? I mean, I can't believe that he has never fought people bigger and stronger than him, yet he always comes out on top.
Again, I'm not disputing what you're saying, just simply looking at it from a different point. IMO, when you have people close in skill/strength, I would think it would turn into more of a chess game. Who can out think the other.
