That takes me back. I was at that event with a friend. We were karate-ka that had met some Japanese MMA fighters and started working with them. One of the Pride judges ran an MMA gym in Roppongi, and we got floor seats to a bunch of events. I had been to maybe 4-5 Prides and everyone was really impressed with Nog, and we all thought that Nog would end up submitting Fedor.
None of us could believe that Nog took the shots he did and was still conscious. This was Fedor's big "coming out" fight -- until then, no one knew how amazing he really was. It was a great fight, and a great set up for the biggest ever (IMO), Fedor vs Cro Cop.
Everyone I knew became a Fedor fan after he beat Nog, who most people thought they'd never see lose.
