#4 The Undisputed ERA
While The Shield dominates the main roster, there is a group in NXT that rules the roost known as The Undisputed ERA. They are brash, they are arrogant and they are all gifted workers. They all have the potential to be top guys in the main roster, if aligned as a heel unit. And what better way to make a first impression than going after the top dogs in the promotion?
Why I am so invested in this feud is because of how good the matches will be. Not only will it make sense from a storyline perspective (heels from NXT who've won all the gold want to claim the top position in the main roster), The Undisputed ERA can put on some great classics with The Shield. It would be a treat for casuals and smart fans alike.
The Undisputed ERA consists of four superstars who're not as big as the guys that Vince McMahon is known to traditionally push. Having them defeat The Shield right off the bat,with the advantage of their increased numbers, could be the only way to see them in a certain light!
