#3. Working heel
CM Punk spent more time as a face than as a heel in WWE, but that’s not necessarily because he was better in a good guy role. Despite his relatively small size making him a natural underdog, and his straight edge sensibilities making it easy for WWE to push him as a role model, there’s a real argument to be made that Punk was only a face because he was so good in his heel work that fans wouldn’t boo him.
Working in AEW could press the reset button for Punk as he re-embraces his more villainous side. He’s a wicked heel promo, and while he spent much of his WWE run portrayed as an upstart, in AEW he could readily transition to more of a veteran legend spot and become the mountain for less established faces to overcome as they work toward their rises to full blown stardom.
