I think people are making a lot of broad statements regarding how the rematch plays out based on a few minutes of sharp, impressive, destruction via Rose. The fact is though, based on what we've seen from Joanna against some highly credible fighters like Andrade, Clauida, and KK, I think it's tough to be overly confident in how a rematch plays out.
Maybe the best version of Rose is and always will be better than Joanna. Maybe Rose is the worst stylstic matchup out there for her. But maybe also Rose doesn't land the vicious shots she did in the first bout and Joanna beats her up in the clinch and wears her down over five with superior cardio (not doubting Rose's own conditioning as she tooled Paige for 23 minutes but we know Joanna can go at a nasty clip in a fight that doesn't start as completely one sided).
My basic feeling is that the most problematic part of the Rose matchup for Joanna is that Rose is one of those blood in the water type fighters who will really go for the kill when she is in a position to do so. Joanna, in turn, seems prone to getting wobbled or hurt at this stage.
Factor in one other element- the type of fight Joanna likes is the type of fight that leaves her vulnerable to eventually getting shut down. If she were someone who mixed in grappling with her striking then Rose might never get traction or have more to worry about. But because Joanna single-mindedly uses her grappling defensively, Rose really could be losing a one-sided striking match to Joanna's volume but eventually, over the course of a prolonged fight, land the bomb she needs to floor Joanna and then pounce.
That said, I have faith in Joanna's ability to learn and come back from adversity. Interested to see how a rematch
plays out and I don't emphatically see it as a Rose win despite how awesome she did in the first fight.
