8: The Usos
Fixtures of WWE television since 2010, the Usos have the longest uninterrupted tenure of any team on this list. Joining the main roster in 2010, the team has feuded with practically everyone, winning their first of five Tag Team Championships in 2014.
Despite spending years as admittedly, bland babyfaces, the team of Jimmy and Jey have always impressed with their aerial offence, and certainly added a new dynamic when then turned heel in late 2016.
Now with a new mean-streak and attitude to themselves, the Usos have continued to impress on SmackDown Live, with both men being happy with their roles as tag team wrestlers.
Perhaps they will eventually split in the future, though we can't see it happening anytime soon, as the Usos prove that blood is indeed thicker than water.
