2. Daniel Bryan and Summerslam 2013
Daniel Bryan is one of the best technical wrestlers in the world and everybody loves him. He is capable of being in the main event on a regular basis, but unfortunately, WWE did not use him right during 2013.
At Summerslam 2013, Bryan defeated Cena to win the WWE World Heavyweight Championship, and the fans were looking forward to watching Bryan's run. Suddenly, Triple H turned against Bryan by attacking him and then letting Randy Orton cash in his Money in the Bank contract on the same night, ending his reign within minutes.
This all resulted in giving us one of the most memorable Wrestlemania moments, but that was not the exact plans of the management.
Originally, Daniel was supposed to feud with the Authority for a while and then was supposed to move on in a feud with The Wyatt Family, which did happen for a brief period as Bryan joined the Wyatt Family for a short while.
It was because of the massive public outrage that Daniel was given the championship at Wrestlemania 30. But, it raises the question of what WWE thinks of their wrestlers.
