Kron Gracie vs Otavio Sousa.
It's a rematch of a heated finale from the brown belt worlds just before each of them graduated up to faixa preta.
Kron took it by mounted collar choke from Otavio after an early sweep by Otavio and a failed transition to kneebar. Kron always goes for the finish and Otavio has looked absolutely on fire since turning up at various IBJJF tournaments as a black belt. I'm actually more excited for this than Roger and Buchecha

Incidentally, Otavio (along with the Estima brothers) got his start at Gracie Barra Pernambuco where I trained while in Brazil.
