Antonio Rodrigo Nogueira, who officially retired to take an office position with the UFC in Brazil, won championships in the UFC and Pride FC, and at one point, was considered the best fighter in the entire sport.
But his most memorable moment came against a fighter that nobody would take seriously today, but was taken very seriously at the time.
It was Aug. 28, 2002, and there were 71,000 fans in attendance for a Pride show at the outdoor Tokyo National Stadium, which to this day still stands as the largest assembly in MMA's history.
