At UFC 168, Rousey put on a judo clinic, throwing Miesha Tate to the canvas six times in less than three rounds.
In her throws, the champion has some of the most effective takedowns in the women's bantamweight division. However, on Saturday, Rousey will meet the best female wrestler to ever enter the Octagon and quite possibly the only fighter in the 135-pound division capable of beating her when it comes to takedowns.
McMann put her wrestling on display in her UFC debut, taking Sheila Gaff down twice in less than one round en route to a ground-and-pound win. The world-class freestyle wrestler has also already shown the ability to shut down judo techniques and counter them with takedowns of her own.
At ProElite 3, Hitomi Akano repeatedly attempted a koshi guruma against McMann. However, the American recognized the throw immediately, sunk her hips and dumped Akano onto her back to score several takedowns.
Notably, McMann finished most her takedowns in that matchup by landing in half-guard or side control. It will be important for her to do the same against Rousey, who would be forced to regain full-guard before she can threaten with armbars.
Rousey has been able to toss other opponents around the Octagon. She won't be able to do the same against McMann, who should have an edge in takedowns. Whether going to the ground will be a smart decision for McMann could be another story.
