I think the only way Tate can beat Rousey is by decision. Tate hardly knocked out anyone. If she can survive her armbar, then I think it is possible for her to win the fight. In striking, Tate can be competitive. Otherwise, I see no chance for Tate. I still think Amanda Nunes is a better contender because she finishes fights (TKOs or Choke). Watch her vs Julia Budd or Sara McMann. Tate is defensive and just wants to survive Ronda's armbar.
