Ronda Rousey has already accomplished everything she needed to accomplish in MMA. She was one of the greatest champions in the company's history and had a dominant run as the most dangerous woman in MMA. She has no reason to further risk her legacy, or her health by continuing to grind through the sport. A move to WWE would be great for her.
Rousey already made a special appearance at Wrestlemania 31, much to the delight of WWE fans. She proved she has the chops to cut it in WWE, and the star power to be a popular crossover sensation in professional wrestling. With a little more experience, Rousey could be a franchise star for the company.
Rousey may have had a string of bad matches in the UFC, but it doesn't mean she should quit. The world loves a comeback story. Rousey has an opportunity for her own. She shouldn't deny that chance for an easy paycheck with the WWE.
After losing her last two matches, Rousey has unfinished business in the UFC. If she is a real competitor, she wouldn't let those losses stop her from coming back and taking over the sport again. At 30 years old, Rousey has enough left in the tank to climb back to the top of MMA once again.
