She had the perfect gameplan vs Ronda that's for sure, and I agree she was very classy in the whole buildup to the fight and has been ever since too. Much respect.
It'll be very interesting to see how she matches up against other opponents, she's only really had two other fights in the UFC, both against mediocore-level opponents and while she beat them, they weren't exactly convincing performances (the Pennington fight in particular).
They'll have to book the rematch against Ronda because the UFC likes money and that fight will make them a lot of it.
How that rematch plays out though depends almost entirely on Rousey IMO - whether she changes camps / coaches in particular, or demonstrates in some way that she's come up with a viable game plan. Because it looked for all the world like she had no idea what to do against a mobile southpaw, and no Plan B for when "bum rush into the clinch" failed.
