I had the TheMat feeds on and was watching when a friend came over. If have a 24 inch graphic arts monitor that shows well. He sat through six matches, asking questions from time to time. As he left I asked what he thought.
"boring, all they do is push each other. What's with the pushing a guy out to get a point? Life his leg and run for the edge? how lame. Sumo at least has some kind of show involved. How come only their friends or parents are in the stands? Not much is happening and the referee keeps making them stand up. How come the bottom guy just lays there?"
To say he was not impressed is an understatement.
He has seen some High School matches and is not completely unfamiliar with the sport. Safe to say he won't be watching much Freestyle or Greco in the future.
