9. The Hart Dynasty - 146 Days
The Hart Dynasty are a team that as we career into the future many will lament the lack of focus given to them. The duo, aligned with Natalya (daughter of Jim 'The Anvil' Neidhart) were such a no-brainer to put together that it was quite frankly baffling that it wasn't the only plan for either man from the off.
DH Smith, son of the legendary British Bulldog Davey Boy Smith and Tyson Kidd, the final graduate of Stu Hart's infamous dungeon, finally tasted tag team success in 2010 when they defeated ShowMiz for the straps. Even this was fairly bungled, as many felt it would have made more sense for Smith and Kidd to defeat D-Generation X for the titles, to give some semblance of finality to the Bret Hart/Shawn Michaels story.
The title reign of the Dynasty didn't set the world alight, either, as the duo feuded with the Usos before dropping the belts (to Cody Rhodes and Drew McIntyre) in a Tag Team Turmoil match at Night of Champions. In fact, the only thing of note from their 146-days was that the copper penny belts we know and hate today were introduced at this time.
