Sara controlled it throughout. ... IMHO, she is more advanced standing that Rhonda is at this point. Great job Sara.
What exactly do you base that opinion on?
You can't compare McMann's striking to Rousey's because ,... well .... because you've never seen Rousey's striking.
The fact of the matter is that NOBODY knows how good (or bad for that matter) Rousey's stand up is because NOBODY has seen it yet. And NOBODY has seen it yet because NO opponent has managed to remain standing after first clinch with Rousey.
Frankly at this point part of the fun in watching Rousey is to see who will be the first fighter to survive the 1st minute (let alone the 1st round). Or who will be the first fighter to take Rousey out of her comfort zone (judo) and force her into a striking excahange.
