If we are talking about the same guy, I think we all will take your word that hes a good guy and just let the thrill of victory captivate him. That is entirely understandable. Nobody is saying his wins arn't legit or he didnt deserve them. Again, my complaint about his back flip was because it was very clear his opponent was actually injured and it bothers me alot to see people celebrate when that is the case. Also, on saturday he had kicked some chairs in a fit when he lost in the gi.(I did not witness this, but multiple tournament staff told me it took place and they were displeased with him because of it). I do not know if there was any circumstance to that other than being a poor sport, but I do understand how upsetting a loss can be as well -- but still he is better off curtailing that behavior. It seems like hes just the kind of guy to be emotionally attached to his matches: upset when he loses, excited when he wins, 100% understandable, but he should really consider how acting those out can reflect upon him to others.
