possibly meant 61kg to align with the UWW weight classes, but either way it begs a few questions:
1) Will Joey be competing at 57kg regularly as planned?
2) (jokingly) is the food that much better in Chicago making Joey want to move up the weight?
My guess is that its a one time move for JD, glad to see him getting the matchup, and hope he does well. I look forward to seeing him compete at more freestyle events.
