#1 The Revival

Finally, at #1 on the list, we have none other than The Revival. Without a shadow of a doubt, The Revival is the most undervalued team in the Raw Tag Team division today. The duo had dominated in NXT, as they proved time after time that they could put on fantastic matches. Dawson and Wilder had even won the 2016 NXT Match of the Year award for their exceptional Two out of Three Falls match against #DIY at NXT Takeover: Toronto.
But on Raw, WWE has yet to pull the trigger on the duo winning the Raw Tag Team Champions. They had debuted on April 3rd, 2017 episode of Raw with so much hype after they defeated The New Day. Fast forward to 2019, and that same hype isn't really there anymore.

However, despite the shocking booking of The Revival, they remain consistent in the ring as seen during the 7th January 2019 episode of Raw when we saw them go head to head with Chad Gable and Bobby Roode in a Lumberjack Match for the Raw Tag Team Champions. Both teams arguably put on the best match of their Raw careers as a tag team, despite the controversy at the end of the match when Dawson had his foot on the ropes.
They are currently embroiled in a rivalry with Roode and Gable, and there is no perfect time than to have The Revival finally come out on top with a Tag Team Championship win over the current champions.
Despite the fact that The Revival play heel characters, there would be no doubt that whatever arena they're competing in would go absolutely wild to see The Revival be crowned the WWE Raw Tag Team Champions for the very first time in their careers, as they definitely deserve this opportunity out of all the tag teams on Raw.
