Much has been made of CM Punk's increasingly historic WWE title run. As Punk approaches a full year as champ, he will inevitably be compared to the all-time greats, but WWE history boasts wrestlers with far more extraordinary reigns.
Other champions have held their belts for 2803 days, for 28 years and other reigns at least twice as long as Punk's. Wrestlers have gone undefeated for long stretches to open their career or at the Super Bowl of wrestling.
These displays of dominance will never happen again.
WWE is a different beast now. Had some of these runs happened today, fans would have sneered at how strong the wrestlers were booked, labeling them "supermen" and lamenting all the wrestlers he was "burying."
Fans can only look back at WWE's greatest feats of longevity in awe.
