Okay I know we haven't seen every "important" member of big mom's crew. But just we the few members that we have seen so far, let's invent match ups!!
My guess is obiously:
Luffy vs Big mom
Zoro vs Bobbin
Sanji vs Baron Tamago (leg fight)
??? vs Pecoms
??? vs 3 eyed girl
maybe Big mom's crew is very similar to WB's crew, putting commanders in charge of small crew's aqnd probably every Straw hat member will fight against a commander.
Give your opinion guys.
