#2 WWE and MMA
Shayna Baszler's success in NXT has been phenomenal. WWE has relied on mixed martial artists switching to a comparatively more safer form of sports entertainment, professional wrestling. The likes of Matt Riddle doing a brilliant job inside the ring is a testimony to the kind of wrestlers that can evolve out of MMA for WWE.
Brock Lesnar defeated Kofi Kingston in seven seconds on SmackDown's premiere episode on FOX to establish the Blue brand as an equal competitor to Monday Night RAW. Lesnar's MMA background helped FOX restore it's more sports-oriented broadcasting and also provided room for WWE to sign more MMA fighters.
It allowed for a once in a lifetime match between former UFC Champion Cain Velasquez and WWE Champion Brock Lesnar in a sequel to Lesnar's loss at UFC 121 against Velasquez for the UFC Heavyweight Championship.
WWE did everything right in the buildup to this match. They were able to capitalize on WWE veteran Rey Mysterio which resulted in an incredible rematch between Mysterio and Lesnar as wll. The last time when both these wrestlers met, Lesnar submitted Mysterio for the win. WWE gave a beautiful picture to the WWE Universe to cherish forever. Lesnar redeeming his UFC loss by submitting Velasquez via kimura was indeed a sight to behold.
