I think Joanna Champion will have problems striking with Thug Rose. Joanna is a stiff, straight-line 1-2 puncher, while Thug Rose also has lateral movement (which confused Joanna in the first fight, and made hesitate into a KO).
Striking is going to favor Thug Rose, and the grappling is going to favor Thug Rose. Joanna has to clinch and press Thug Rose against the cage, like Karolina K did.
Joanna has to be a very different fighter to win, while Rose can win just being who she is. It doesn't look good for Joanna Champion.
