#1 Undisputed Era (SmackDown Live)
Adam Cole is the leader of arguably the most successful faction in modern professional wrestling. The Undisputed Era consists of; Cole, Kyle O'Reilly, Bobby Fish, and Roderick Strong. Together they have dominated the NXT brand.
Moreover, they garnered a multitude of achievements. Notably winning; Dusty Rhodes Classic 2018, North American Championship, and two NXT Tag Team championships amongst them.
At NXT Takeover: WarGames Undisputed Era once again will participate in a WarGames match. They face off with; Pete Dunne, Ricochet, and War Raiders (Hanson & Rowe). It will be an entertaining match. Moreover, it provides an opportunity for further success. However, the Era's tenure is coming to an end.
Presently, SmackDown Live is flourishing. Primarily due to performances from New Day, AJ Styles, Daniel Bryan, and other talents. The addition of Cole's group would be pivotal to SmackDown's entertainment value.
On Raw, The Shield was excellent and garnered mass interest. Undisputed Era's presence would be no different. Therefore, this needs to happen soon. Just imagine a standoff between Cole and AJ Styles, two former Bullet Club leaders.
