If she takes the Holly Holm approach, it would take 4 years between making her MMA debut and challenging for the UFC title. I have no idea how long Holm started grappling before her debut.
Holm just runs away and pot shots and got exposed by Cyborg and Nunes, she beat Rousey because Rousey had a lousy trainer and was a one trick pony.
No, she had no stand up game and looked plain stupid in there with two experianced stand up practitioners, Rousey could have been an all-time great because of her amazing judo talent, but on her feet she was useless as was her trainer: "head movement!" "head movement!"
So any mixed martial artist that has ever lost a fight has been "exposed" according to you? Otherwise, I don't know what point you're trying to make with these posts.
