It's all very interesting because, as we all know, the only gold medalist in the group ended up being heavyweight, Bernardo Faria, who beat Xande in a gnarly final. Kayron medaled too, with a third place finish in his division.
My analysis and observations? Only that we all love jiu jitsu and the great champs who compete at it's highest level. These guys are all great and have great futures in BJJ - some had tough breaks (bad calls, bad days) and some had great moments. Hail to jiu jitz!
