CM Punk stepped into the WWE in 2006, and has since had a meteoric rise to stardom. Possessing limitless potential, and a well needed straight-edge gimmick, CM Punk's legacy has only begun in the WWE. After holding multiple titles, including the Heavy weight championship, it's safe to say that Punk isn't going any where any time soon.
The Positive: CM Punk has a smaller physique compared to other world champs which makes for great story on WWE's part. For one, bigger guys look at him as easy prey. Two, not everyone out there is shaped like Batista or Cena. Realistically speaking, Punk has a regular guy's body, well, a little toned maybe. Over the last year or two, it seems as if WWE is looking for smaller talent to push. Morrison, Ziggler, Bourne, are just a few rising stars that step away from stereotypical 300lb wrestler.
Punk's gimmick is great for this generation of wrestling. Kid's need sum1 to show them that they can make it without taking the wrong side. Like Cena, Punk is hit. There's a reason why WWE made him champ. Not only to start something fresh, but to show how far this young star could go.
Negatives: Punk's negativity is based strictly on how he won his titles. In a way, emulating Edge who constantly stole titles from already beat superstars. Punk, according to his gimmick, could have been above this. He could have put on a believable match, and won the title fairly. It takes away from his character, and pushing him more as a heel (while good) only furthers the idea that he's mirroring Edge. In the end, an opportunity is an opportunity and Punk rose up to the occasion.
In conclusion, Punk's rise solidifies him as a next gen. trailblazer during WWE's PG era. Expect to see more of him.
