Holy Moly. I was impressed that Josh Waitzkin could hold national chess championships and world PH championships and now aims for world BJJ championships. Egan Inoue has won multiple world racquetball championships followed up by multiple world BJJ championships. He also won mma world championships, though I can’t find with what organization. His younger brother was heavyweight champ in Shooto and competing in mma when he called Egan to stand in for him for a match, leading to his next sports career. Geez.
