#4 Target a body part
Another great way to chop Ronda Rousey down to size is to once again give her a storyline injury and have Nikki exploit it before and after the match. At least this way Nikki can believably stand toe to toe with Rousey and also gain a little heat every time she intentionally injures the champion.
In the end, targeting a body part, especially something like her arms or legs, would be a great way to slow Rousey down and make her focus on her power game to beat Bella. With Rousey slowed down and Bella targeting a specific body part throughout the match, it will create an opportunity for brutal moves, near falls and the comeback of a lifetime.
Maybe WWE could even have Nikki severely injure Rousey before the match and even put in doubt whether she can compete or not. Not only would that create a lot of mystery leading up the big pay per view, it also helps add to the story of Rousey not being 100 percent when the match does actually take place.
