Sounds like IOC being political again. They keep certain sports that favor certain countries and eliminate others. Softball was eliminated because US and Canada dominated. Rugby used to be a sport, but only a few countries did well. I would keep wrestling because a lot of countries do it and some, like Mid-east and Eastern Europe, excel at it. I would ditch, synchronized swimming (just dumb), Rhythmic gymnastics (Russia always wins), ping pong (China always wins and only a few play), synch diving (just too much).
I would also ditch Men's football (soccer) unless FIFA let's the teams field all the best players.
