5 former superstars the WWE should bring back

#2 CM Punk

It's clobberin' time!

When CM Punk abruptly left the WWE in 2014, he was still red hot and at the top of the main roster. However, he had expressed his concerns regarding the creative future of not only himself but the future of the company as a whole. Essentially, Punk felt as if his concerns were falling on unresponsive ears.

Punk would go onto pursue a life outside of professional wrestling. He would start working as a writer for Marvel Comics, which had been a dream job situation for Punk for quite some time.

There was another dream job (so to speak) which Punk had been sitting on for a little while. Punk wanted to try his hand at professional MMA, and after extensive training, CM Punk faced Mickey Gall at UFC 203.

After a tremendous build-up leading to the event, Punk would fall to Gall in the first round, via submission. It's also worth noting that Punk recently lost his second UFC match to Mike Jackson via unanimous decision.

After suffering back to back defeats, it appears now that CM Punk's Mixed Martial Arts career has concluded. While he has stated on multiple occasions that he will never entertain the idea of returning to the squared-circle, there are many who believe there is still hope, especially now that UFC has closed the door on him.
