#2 The Undisputed Era

The Undisputed Era is one of the best things in NXT today. After debuting as a group at NXT Takeover: Brooklyn III last summer, the stable comprising Adam Cole, Kyle O'Reilly, Bobby Fish and Roderick Strong has dominated the entire division winning championships left, right and center.
Within one year of their debut, the group has already held the NXT Tag Championships twice, won the 3rd annual Dusty Rhodes Tag Team Classic and the NXT North American Championship. The Undisputed Era seems to always be ahead of their competition, as was proven during their tag team title defense at NXT Takeover: New Orleans--where the group prevailed against all odds to not only retain their tag championships, but also win the Dusty Rhodes Tag Team Classic.
It, therefore, would be a huge travesty if the WWE were to break up this group and put its members on separate brands on the main roster. The Undisputed Era has a lot to conquer in NXT, including the NXT Championship which is the only title that has evaded the group's grasp in NXT.
