#3 No Legal Issues
Since CM Punk left WWE, he has been involved in a mess of legal proceedings. A lot of it comes down to a tell all podcast with Colt Cabana, in which he openly discussed frustrations with not only WWE’s approach to booking and locker room politics, but also their medical practices. WWE’s Dr. Amann would sue Punk and Cabana for misrepresenting him. In an even less expected turn, Cabana has most recently filed suit against Punk for allegedly lying and reneging on agreeing to pay his legal fees.
Had Punk left in 2011, he may well have been disgruntled. However, with two and a half years less of the WWE grind, and not having the last health scare that he seemed particularly heated about, he probably wouldn’t have left as bitter, or with grounds for legal action on either side. It would be a shame to miss out on some of Punk’s better matches and moments to follow, but that history probably would be cleaner for everyone involved.
