Yall some smart dumb cats. Think about Mundials.
Rafael has first seed. Mario Reis (despite being 0-4 against Frazatto) has a
corner because he's a world champion. Gui gets a corner cause he's a world champion. Who's left for the last spot? Frazatto? Canal? Freitas? Ramos?
Willing to bet it'll be the one with the best track record in recent IBJJF events. Go check the results for Europeans, Pans, Sulamericanos, etc
Ranked according to (all IBJJF tournaments, outside tournaments not considered in gi, absolute ranked higher than weight):
1) Worlds
2) Pan
3) Brasileiro
3) Europeans (Europeans is catching up in prestige to the Brasileiro, so I put them as tied)
4) Rio Open
5) Sulamericano
6) Random US tournaments
Watching a ton of black belts define brackets is nerve wracking, by the way.
