As many of you may know, Augusto "Tanquinho" Mendes besides being a world champ, he is also a world class ref. He just posted the following on his Facebook page: "The BJJ Worlds is over and among with great fights I saw one thing that made me worried: it was the referees mistakes! I could see over the days a lot mistakes that made athletes lose their dreams, they trained a lot, dieted a lot, get to their limits to have a bad referee take his dream out. I used to referee too and I know that some referees did a great job, but for me looked like you would need good luck to get one of the good referees in your match. Any way, I saw a lot athletes having problems in their matches, independent of the teams that they represented. The referees have been doing great in past years, they got a lot better in all aspects, but for me the last 2 big IBJJF events (Pan and Worlds) they were definitely worst. I saw referees trying to have more attention than the athletes, I saw the IBJJF judge in different way the same situation (Not taking back the result when the referee said that he made a mistake and than taking the results back in other fights) when the mistake was exactly the same, the referee interpretation! If you didn't have any problems with the IBJJF referees on the worlds I can say that you got lucky! I really hope the IBJJF does something to fix it! Share and leave your comments here!" Beside the Keenan horror story of a call, what have you seen/experienced? My suggestion is that, given the technology the IBJJF currently have, they should allow challenges like the NFL in the BB matches. If the refs call is over turned then they should start back in the position prior to the challenge. If ref's the call is valid, the opponent of the person that called for the challenge should be awarded 6 points. While this may drag on the match, the review time should be limited to 1 per match and 1 min max for the review. Thoughts?
