#4 Chad Gable and Shelton Benjamin
Chad Gable has seemingly gained new life on SmackDown, reaching the semi-finals of the King of the Ring tournament. However, he spent the majority of his main roster career floating between tag teams.
Gable initially found success with Jason Jordan as American Alpha, but Papa Kurt came calling and off went Jordan, thus ending their run abruptly. The former Olympian was soon joined by another Superstar with an amateur background, the returning Shelton Benjamin. They were initially babyfaces but quickly turned heel to feud with the Usos, who were fresh off a classic title feud with the New Day.

They were unofficially known as American Alpha 2.0 and had the potential to build on Chad Gable's previous success. They were technically sound and had some great showings. Gable and Benjamin even looked to have won the SmackDown Tag Team Championship from the Usos, before the dreaded instant replay halted their joy and the referee overturned his decision.
The eventual feud-ender did not go as planned, as the Usos swept them in a 2 out of 3 Falls Match at Royal Rumble 2018. Gable and Benjamin did not do much of note during WrestleMania season and they would be split during the Superstar Shakeup.
Benjamin stayed on SmackDown and Gable moved to Raw. Honestly, WWE could have done with more credible tag teams on either brand at this point, especially after the Raw Tag Team Championship was won by a 10-year-old boy at WrestleMania.
