CM Punk's abrupt exit from WWE left fans wanting more. There was so much left for the star still to achieve in WWE, there was a whole range of possibilities he could have benefited from. Obviously Punk didn't agree. He took off from WWE in January, following what Paul Heyman described as a discussion with Vince McMahon and Triple H. Could he ever return to complete his legacy? We can't rule it out, particularly after a WWE Raw script leaked which listed Punk as a miscellaneous talent out injured with a comeback to be determined. Was this just a peculiar coincidence of the script, or is Punk genuinely injured and still in the WWE picture? Time will tell. Before we get into what Punk could still achieve with WWE, let's talk about some of the things he has already achieved. He was a tag team champion, an intercontinental champion, a two time Mr Money In The Bank, a three time World Champion, and a two time WWE Champion. Considering all of the creative invested in Punk, he hardly had cause to complain, he was five times the Champion, in some ways he should have stuck around in WWE to pay back their faith in him. Especially considering he spent 434 days as WWE Champion, the longest reign of the modern era, he could hardly complain about creative after that huge investment in his character. Hopefully Punk rethinks things and we see him get back on board with WWE. Here's 10 achievements he still needs to make.
