#1. Hasn't disappointed: CM Punk is elevating younger stars immediately
Perhaps the best thing that CM Punk has done since his arrival to AEW is the instant elevation of young talent. The first Superstar's name he used was homegrown talent, Darby Allin.
By simply sharing the ring with Allin at ALL OUT, he elevated the young star to a whole new level. While Allin was always considered among the 2-3 hottest homegrown talents of AEW, associating with CM Punk in his first match back did wonders for his popularity.
Although the young talent that CM Punk has faced all lost to him, a win over the legend wasn't needed. Darby Allin, Powerhouse Hobbs, and Daniel Garcia all benefited from sharing the ring with him.
Matt Sydal isn't a young talent anymore, but he also benefited from his match against CM Punk at Rampage. Not only is Punk easing himself into AEW and wrestling again, but he's helping elevate younger talent in the process. It's hard to find any criticism with that whatsoever.
