Lemos (ranked 3rd) should fight Rose (2nd) because she shouldn't get a title shot without having beaten any of the three elite fighters of the division (Rose, Weili, Andrade) or even Carla, little less when two of those fighters are ranked ahead of her.
Andrade (6th) should fight Carla (1st). Even though Jessica is ranked lower than Lemos (3rd) she has already beaten her so she deserves a higher ranked opponent than Lemos would get....plus the lower rank is only because she keeps yo-yoing between divisions.
If Andrade and Rose win (most likely) then they should fight each other for a third time (an exciting match-up!) and the winner should get a title shot and that way you avoid both a Rose vs Weili 3 that would be a bit too soon as well as Rose and Andrade not settling who is better after all.
If Andrade and Lemos win they should each get a title shot one after another just to have a bit of variety when it comes to title fights.
What do you guys think?
