#3 The Miz
CM Punk is known for speaking out his mind and at certain instances he speaks from a fan point of view. This is what made him a hit in the WWE Universe but at the same time, this earned him a lot of enemies backstage. One among that was Miz.
Punk was not happy about Miz heading WrestleMania 27 alongside John Cena, and went public with his opinion. He stated that he should have been in place of Miz at the pay-per-view and it clearly pissed The Awesome One off. Miz however restrained from making it a big problem and deserves some credit for that.
Punk on the other hand, continued to make similar comments about the Miz and ended up looking like the bad guy even though he was speaking out what the fans felt.
