TJ would beat her senseless and in very short order. Ronda is a fantastic athlete, surely the most dominant fighter we have ever seen, but she would be slower, weaker and vastly inferior in striking and wrestling technique. She would have absolutely no chance.

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.

If Ronda tries to stand and fight TJ, like she fought last night, he would defeat her extremely quickly. Compare their movement and footwork in recent fights -- it's not remotely comparable. It might not be quite as one-sided if she can bring it to the ground, but I'd still expect his strength to dominate before long.

It's disappointing that we'll probably never see Ronda realize her full potential because she doesn't face enough competitive pressure.

> I don't think TJ Dillawshaw (current Men's Bantamweight > champ) vs Ronda Rousey would be a decisive victory for TJ.

It won't be decisive. It would amount to an assassination. I'll let you figure out who would kill who.
