"I've prepared for the worst-case scenario," Rousey said. "I'm constantly talking her up, that she's going to be in the best shape of her life, that she's going to have a perfect game plan. I've spent this whole camp focusing on every single weakness I could possibly have. I assume she's going to be … a perfectly trained athlete … that's going to fight me for a five-round brawl."
Rousey hasn't fought since February and has since co-starred in "The Expendables 3" with Sylvester Stallone, and she'll also appear in "Fast & Furious 7."
Tate said that Rousey is vulnerable, in part because of her layoff and the distractions of stardom.
"A lot of people build Ronda up to be this invincible person, but I don't see it that way at all," Tate said. "I see a lot of holes in her game and I see a lot of ways that she can be exploited. Just because it hasn't happened yet doesn't mean it won't ever happen."
Rousey said her conditioning is fine after a six-week training camp that included workouts on the film set, such as running the hills of Bulgaria with her "Expendables" co-star, boxer Victor Ortiz.
"She expects me to go out and make stupid mistakes and gas out," Rousey said. "I'll be better prepared."
