On August 28th 2015, at the ADCC in Sao Paulo, two legends of Jiu-Jitsu which were formed by the late Carlson Gracie locked horns: Ricardo Liborio and Mario Sperry. Liborio came out on top with a victory by referee decision.
In an interview with Sherdog.com, Liborio, leader of one of the largest MMA gyms in the world, the American Top Team, discusses his win at ADCC 2015 and the legacy of Carlson Gracie.
