Even though staged is not the right way to put it, there is no getting away from that Carmouche is getting fed to Rousey. If the UFC really pushed for it, they could likely get the Cyborg fight for the card, but the UFC wants to show Ronda getting a W on the big stage. Ronda is far and away the most marketable fighter in the division, and without her Dana almost surely wouldn't have bothered introducing the female division.
205, 185, 170, 145, and 135 all have or, had dominant Champs since Cruz's future is in the air, Heavyweight will likely have another one and people still pull out their wallets to watch those champs, so what makes the Women's division different than those?
I mean, does anyone really believe Bisping can beat Silva? Sonnen can beat Jones? Diaz can beat GSP?
