Absolutely no reason why, but I think it might be Torres. Rawlings could land the harder shots and steal a split or some shit.
Out of the 12 upcoming fights Torres is the least likely loser imo.
1. Bec couldn't make weight, she said herself that she pushed her body to it's absolute limits to try to hit 116 & her body failed her
2. Bec has 2 kids and is fighting out of Australia
3. Bec got finished by PVZ in her last fight
4. Becs last two wins both happened in Australia
5. Becs does have the power advantage, yes, but all she ever got was one knockout (in 2011 against a nobody)
6. Becs last finish was in 2013 against Jasminka Cive, who is very very bad in MMA (I am from Austria, I have seen her live - Torres would also finish her easy in round 1)
7. Bec has the same nickname as Ronda and I could imagine her also being kind of unstable
8. Tecia is a lesbian, and lesbians are on a roll right now (Nunes, Ansaroff, Pennington)
9. Tecia obviously has no weight cut problems, cardio is also not a problem
10. Tecias fighting style is very reliable, it's hard to imagine her doing something flashy and getting caught for it
11. Tecia did lose her rematch with Rose in a close fight, a loss in her rematch with Bec would put her far away from the title picture
12. Tecia has never been finished, I believe she wasn't ever close to getting finished either
13. Tecia is way shorter and has less reach, but that's nothing new for her, she is 5'1" (same as Rin Nakai). Danielle Taylor is the only UFC fighter shorter than her.
Take some of those 13 points with a grain of salt
Wwho knows, maybe Bec will get lucky and knock Tecia out with a switch kick - but I highly doubt it.
I rate the upset potential for Herrig and Hill higher (I won't take a stab on them though)
