#1 Shouldn't: CM Punk
The second that AEW was announced, fans began to speculate: will CM Punk join? And I hate to break it to those fans, but the answer is seeming no.
Punk, who left the WWE in January 2014, has made it clear that he does not intend to wrestle ever again, instead focussing on his MMA career, where he is 0-2.
Whilst fans are certain that Punk will eventually return, the Voice of the Voiceless has cut ties with several friends of his in the industry, and is even involved in a lawsuit with best friend Colt Cabana.
Even when Rhodes and the Bucks hosted ALL IN, their independent supershow, in Punk's hometown of Chicago, Illinois, Punk didn't show, perhaps the most damning statement that he has hung up his kick pads for good.
