Cat is the most overrated fighter in that division. Miesha was her only legit opponent and dominated the first two rounds before she got caught. I expect her to drop like Carmouche did and become a solid fighter in the division but not a contender.
If the Dec. card had a third title fight, I don't think they'd put TJ v Cruz which has enough drama to be a potential headliner fight. Maybe they'd give JJ v Gadelha that slot though, it's a new division that needs fan fare, the card already has a Euro v Brazilian massive fight, so this could draw from those two fan bases even further. That wish list is massively stacked, imagine the opening fight on any card being Romero v Souza!? That'd have to be an epic card. I doubt it's realistic to expect that though, they'd probably put a couple of up and comers on instead to try and build their names.
