Is Adam Cole at AEW All Out 2021 a possibility? If reports are to be believed, it's only a matter of time before Cole heads to AEW and becomes part of the roster.

We all know that Adam Cole is in a relationship with the AEW Women's Champion, Dr. Britt Baker. Could we see Cole show up and help AEW's resident dentist pick up a victory at AEW All Out 2021 and help her retain her Championship?

#3 After the AEW All Out 2021 bout between CM Punk and Darby Allin, Bryan Danielson shows up

Speaking of free agents, Daniel Bryan, as Bryan Danielson, could certainly revisit his rivalry with CM Punk. These two men have waged many wars in the past, just never in an All Elite Wrestling ring!

Could we see these two living legends square off at AEW All Out 2021 in order to set up a match further down the road? What a sight it would be to close out the show, should the Punk-Allin match go last. Maybe the two men even get into some kind of tussle to hype us up for the next episode of Dynamite.
