There's money to be made on this. For me Rose beats Jessica
Rose is taller, longer reach, if Joanna was to keep Jessica at distance there's no reason why Rose wont be able to, and even if it does go to the ground Rose's ground game is a long way beyond Joanna's and JJ was still able to stop the take downs and win comfortably.
There's also the factor of it being in Brazil. people assume that this makes it harder for Rose, "going into enemy territory", but it could be quite the opposite.
All the pressure will be on Jessica. The local media are going to be all over her wanting interviews, comments, while Rose will probably get largely ignored (which is just how she likes it). Then on the night, all the fan pressure will be on Jessica, main eventing in Brazil.
There's every chance that Jess could get caught up in it all, and either pull an Aldo and go all out in the opening seconds and get starched, or, she goes too hard to early and has the mother of all adrenaline dumps in the second round.
Everyone presumes that it being in Brazil is a huge disadvantage to Rose and a big advantage to Jess. I think it could be quite the opposite.
