#2 Vince McMahon is giving Baron Corbin a push

Baron Corbin defeated Roman Reigns at TLC, much to everyone's surprise. It didn't really hurt Reigns' aura, but it did improve Baron Corbin's image as one of the biggest heels in the company right now.
No matter how many Superstars help you, if you are able to beat Vince McMahon's golden boy Roman Reigns, you are doing something right. That is what is happening with Corbin at the moment and with this win, he may have strengthened his position as the company's best heel.
Also, this has helped Roman to get over with the WWE Universe, as anyone who comes up against Corbin will always be cheered. King Corbin will get a championship opportunity down the line and he will be heavily involved in Reigns' character arch as we approach Royal Rumble.
There's a chance that Corbin vs Reigns will continue until then, but don't be surprised if Corbin and Reigns move onto bigger and better things.
