#8 Mustafa Ali (United States Championship)

Mustafa Ali has been WWE’s surprise package. Ever since his amazing Cruiserweight Championship match against Buddy Murphy at Survivor Series, Mustafa Ali has received a much-deserved push to the main roster.
He evened scored a pinfall victory over WWE Champion Daniel Bryan on Smackdown Live. He has shown a lot of heart and WWE are very slowly pushing him without any indication.

Just look at his recent performance in the Royal Rumble match. He lasted 30 minutes before finally being eliminated by Nia Jax. During the match, he even eliminated Samoa Joe.
If WWE pushes him for a title run, they may most likely consider the United States Championship as the most viable option.
#7 The Undisputed Era (RAW/Smackdown Live Tag Team Championship)

The Undisputed Era has been one of the best tag teams in NXT. They have been consistently wooing audiences with their amazing matches and it seems like their hard work might pay off this year.
After losing their NXT Tag titles to the War Riders at NXT Takeover: Phoenix, it seems like The Undisputed Era will be brought up to the main roster following WrestleMania.
For quite a few months, the tag team division on the main roster has lacked a lot of depth. The Undisputed Era could help breathe a breath of fresh air in WWE’s lackluster tag team division.
When they finally make the main roster, WWE will waste no time in putting them in the tag team title picture. However the story unfolds for them, it looks like a title run could definitely be in Undisputed Era’s future.
