#7 Road Dogg - 13 Years, 11 Months
WWE Hall of Famer, The Road Dogg, certainly had the best years of his career as apart of D-Generation X, and the New Age Outlaws. When teaming with Billy Gunn, the duo originally held the WWE Tag Team Championships on five separate occasions, before splitting up in early 2000.
The Outlaws had entered the century as Tag Champs, but would lose them to the Dudley Boyz at No Way Out in February, 2000. During the same match, Billy Gunn suffered a serious shoulder injury that would keep him on the shelf until October. While he was away, the Outlaws quietly split and Road Dogg was released by WWE in early 2001.
Road Dogg eventually found his way back to the WWE in 2011, taking a position as a producer. He and then fellow producer Billy Gunn began making special appearances on WWE TV and were briefly written into storyline, which incredibly saw them defeat Goldust and Stardust for the WWE Tag Team Championships on the Royal Rumble pre-show, over 13 years since they had last held them. They eventually lost the titles to The Usos that March.
During Road Dogg's time away from WWE, he wrestled for TNA for seven years, where he was a two-time NWA Tag Team Champion. I am only including Road Dogg in this entry and not Billy Gunn, as Gunn's last title reign in WWE before this was in 2002, when he and Chuck Palumbo had two the WWE Tag Team Championship reigns.
