We've seen the gruesome carnage from the sidelines but what's it like to actually step inside the cage with the seemingly unstoppable UFC bantamweight champion Ronda Rousey?
In 12 professional fights only one opponent has ever left the first round, something more to do with Miesha Tate's double jointed flexibility than anything else.
ESPN caught up with six of her past opponents to get their take:
Autumn King, lost via armbar 57 seconds into round 1 on Nov. 12, 2010 in amateur MMA bout
To me, her reactionary times felt as quick as the guys at our pro practice. She was so fast. I trained at Team Quest and I probably only felt an armbar go that fast once before. I think about what would have happened even if I had made it out of the first round.
Charmaine Tweet, lost via armbar 49 seconds into round 1 on June 17, 2011 in HKFC
I have to give her credit in the fight, but not all the credit. I got up from her first takedown. It didn't feel that strong to me. The second judo throw that put me down, though, it was kind of, "Oh. Well, here we are."
Sarah Kaufman, lost via armbar 53 seconds into Round 1 on Aug. 18, 2012 in Strikeforce
I had a game plan of how to win, but that was in my head so much I just wanted to counter what she was doing and if you give up those positions, you're going to lose. She just starts pure 100. She's mentally just on, terrified and fighting for her life when the bell starts.
Cat Zingano, lost via armbar 14 seconds into Round 1 on Feb. 28, 2015 at UFC 184
What I got from Ronda was an actual warrior mode, like you're exposing your heart and putting yourself into a position of vulnerability -- and at the same time, you have complete confidence. I thought it was really interesting, she was the first person that I felt was on the same level as me when it came to that.
Liz Carmouche, lost via armbar at 4:49 of Round 1 on Feb. 23, 2013 at UFC 157
The first thing I think about is how little amount of time I had left on the clock. I had no idea there was 10 seconds left in the round. Had I known, I probably would have let my arm snap.
Sara McMann, lost via TKO at 1:06 of Round 1 on Feb. 22, 2014 at UFC 170
What impresses me is how fast she finishes people. She's going for every chance and she's setting a pace that is really hard for people to maintain. She knows she doesn't have to set it for 25 minutes because she's finishing people.
These were just excerpt quotes. There is way more at the ESPN link. I strongly encourage you to read all the accounts.
