I believe that he has answered all the questions. His matches and workrate in the ring are solid and he too knows how to incite the crowd. By being intense. Intensity is more than just screaming into a mic or beating yourself in the head while you walk to the ring. Intensity is a state of mind.
Intensity is a state of being.
One thing is you cannot be intense if you are unsure of yourself. Intensity is believing in what you are doing completely without fail. Ask any wrestler, football player or anyone else who ever played sports and they will tell you that intensity covers more than just one area. It covers the whole spectrum and if one part is lacking in the whole picture than the whole in of itself is compromised. I am not saying that WCW does not have intense workers.
