#5 Los Guerreros

Eddie Guerrero and his nephew Chavo Guerrero Jr. first broke into the business together thanks in part to their famous wrestling family name. Though they are uncle and nephew respectively, their closeness in age and tightly knit family made Eddie and Chavo closer than brothers. They wrestled in WCW together before joining the WWE.
As a tag team, they were quite successful, defeating many of their contemporaries including world champions such as Kurt Angle. They won the tag team gold on two occasions and were one of the more popular acts on WWE television in spite of being technically heels.
Why they were one of the best tag teams of their era: Eddie and Chavo's 'lie, cheat, and steal' gimmick was so over, Eddie continued to use it when the tag team split up. They almost single-handedly made it cool to be Latino in sports entertainment.
