#6 Heath Slater and Rhyno
While SmackDown had the likes of The Usos and The Vaudevillains on the roster, creative crowned the unlikely pair of Heath Slater and Rhyno as the first SmackDown Tag Team Champions. Slater's free agent status compelled him to align himself with Rhyno and take part in the Tag Team Championship Tournament. Everyone knows what transpired later as WWE effectively produced yet another famous underdog moment.
Slater and Rhyno enjoyed being at the helm of the SmackDown Tag Team Division for 84 days before they lost the titles to The Wyatt Family. During their pairing, the team of Slater and Rhyno defeated The Usos, Breezango, and The Spirit Squad.
#5 Daniel Bryan and Rowan
Rowan shook the WWE Universe by joining forces with Daniel Bryan at the Royal Rumble pay-per-view. He played the role of Bryan’s insurance policy during his WWE Championship reign and when Bryan lost his title, he and Rowan pursued the SmackDown Tag Team Championships.
The duo captured the gold on May 7th, 2019 and dominated the rest of the division for 68 days. During this phase, there was a shortage of tag teams in the division, however, Bryan and Rowan were still exceptionally entertaining. They had had a rivalry with Heavy Machinery before clashing with The New Day.
Bryan and Rowan lost their SmackDown Tag Team Championships at Clash of Champions 2019, but both heels led the thin division well.
