Why did Ronda go into UFC is at the end of the O/P....
All the other stuff she did was great, and it was a good living.
The answer is money. Fighting and dominating in the UFC (for a while, just like any champion, all of them eventually lose as everyone is beatable). Going home, opening a judo school, even if you have the requisite after-school program to keep the lights on, that's merely a "living." Make you feel good, sure. Good for the spirit, and keep you on the mat moving around, laying hands on other like minded folks? Absolutely. Trips to Taahiti in your future? Nope.
The UFC exposure got her paid. And... it got her Hollywood exposure. I think she's been in maybe 3, 4 movies now. Maybe if she's able to ome back, snatch back the title, then retire on top after a successful defense, she can go back to Hollywood and make even more movies.
Without UFC, no movies.
