#2 He became the Longest Reigning WWE Champion of the modern era
If you saw the Money in the Bank 2011 match between John Cena and C.M. Punk for the WWE Championship and didn't get goosebumps, then you surely need to change your taste. Punk's match with John at the MITB PPV was one of the greatest matches that has ever happened in WWE and got a sensational 5 star-rating from Dave Meltzer. The match was a technical masterpiece and moreover, catapulted C.M. Punk to superstardom.
Punk's Championship title reign of a record 434 days made him the longest reigning WWE Champion of the modern era, a record that is still unbroken till this date. It's a damn shame that the Rock ended his reign considering, he was so phenomenal in bringing prestige to the Championship. His honorable work as WWE Champion was monumental in making him the brand that he is today.
