With all due respect, but you have no idea what you're talking about. TJ would absolutely murder Ronda.

There's been plenty of discussion about this on Sherdog and /r/mma... and even some historical precedent. I recall seeing a video awhile back of a then female undefeated kickboxing champion vs a journeyman fighter and while the female fighter showed more speed and skill, the physical advantage made the fight extremely lopsided.
