14Shawn Michaels and John Cena
Shawn Michaels and John Cena had been at odds for many years but back in 2007, they were forced together when they defeated Rated-RKO for the Tag Team Championship on an episode of Monday Night Raw (this of course was not a new angle).
The problem here was the fact that
the duo was also set to fight for the WWE Championship at WrestleMania that year. This added a lot of tense moments between them throughout their few month reign as Champions, but ultimately John Cena defeated Michaels at WrestleMania. As a form of revenge, the following night on Raw, Michaels threw Cena over the top rope in a Battle Royal for their Tag Team titles and cost his own team their belts in the process.
