It's sort of difficult.
McCan shouldn't be in any important fight fight with people who are close to the title right now, if anything she can rematch Miesha.
Pena gets destroyed by both Valentina and Nunes imo, also not sure if she deserves a title shot at all.
Valentina is a tough matchup for the champ, at the same time she's on a one fight win streak and her last loss came to Nunes, if people didn't believe that she beats Nunes they wouldn't call for a title shot as much either.
Honda should come back and fight Nunes, Pena vs Valentina, McMann vs Tate, Holly vs Cat
