It is commonly believed that if you win the major tournaments at purple/brown (Mundials, Pans, Brasilieros), chances are you are going to be a force once you get to black belt. This is true for some of the most successful BB of today.
That said, who do you think will make a big spash on the BB scene once they get promoted to that rank? Off the top of my head here are 3 guys who fit the bill perfectly:
Matheus Lutes (brown) - Marcelo Garcia’s monster brown belt world champ has been tearing up the scene for years. How he isn’t a black belt yet I have no idea lol.
Roberto Jimenez (brown) - I first saw Roberto in Flograppling’s purple belt world championships coverage in which he won the division. He is a back taking machine and one of Alliance’s most promising prospects.
Nicky Ryan (purple) - A kid that trains with the Squad is sure to become an absolute monster in the years to come. He recently earned his spot in the 2019 ADCC World Championships, beating some of the best nogi grapplers in the US.
