One of Ronda's teammates on the 2004 Olympic judo team, Dr. Rhadi Ferguson made the point that no one who has earned a spot on the Olympic team decides not to go, what people do is decide not to train for the Olympics. Karo Parisyan qualified for the 2004 Olympic Trials at 81 kg but went into the UFC instead. He said he never regretted it. Rick Hawn, who won the 2004 Olympic Trials at 81 kg, placed ninth in Athens and is now a fighter for Bellator. He also says he never regretted his decision.
Here is the continuation of the discussion Ronda and I had (with guest commentary from Henry Akins of Dynamix MMA) about whether people really choose the UFC (or anything) over the Olympics - and what do you do after the Olympics is over.
