She should just retire. She has hit her glass ceiling. Even after winning a number 1 contenders match she doesn't get the rematch. She most likely never will. Just retire.
2. You make quite a leap when you conclude that Tate will probably never get a title shot. The public is not quite ready for Tate-Rousey 3, and Holm-Rousey has a short window of viability. The UFC clearly would love to get Cyborg to fight Rousey for the 135 title as well.
She should give the UFC the biggest fuck you ever by persuading them into letting her fight Cyborg and then go outwrestle Cyborg for 3 rounds and while talking to Rogan say hey UFC fuck you for taking my title shot after I beat Jessica Eye and you promised it to me, I just ruined your biggest money fight oh and by the way I am retiring and walk off!
I'd much rather see Rousey/Tate III than Werdum/Cain II.
The correct choice is for Meisha to make a superfight with Cyborg at 140.
If she can pull that off then she makes some real cheddar and has a claim to accomplishing something that Rousey wouldn't (market as - was afraid to) do.
Then she rides into her 3rd fight with Rousey with some real media attention and rakes in the cash.
