Attaining eight matches at SummerSlam, CM Punk proved that he wasn't just a 2011 flash in the pan. Many fans forget just how many years Punk did feature in WWE, with eight years worth of SummerSlam matches being indicative of longevity in star power. Even before his 2011 push, he was already main eventing the show in 2009 against Jeff Hardy. Later in his career, there were even bigger matches. He main evented against John Cena in 2011, and had a classic with Brock Lesnar in 2013. Unfortunately, Punk's eight matches are likely to stay on that number. A WWE comeback in the future is always a possibility, but right now he seems determined to never work in pro wrestling again.
