#1 Darby Allin
While this isn't a match that anyone could have predicted a few months ago, Darby Allin is on the rise in All Elite Wrestling, and given the polar opposites that MJF and he are, this would be quite an intriguing contest.
Allin is a death-defying risk-taker, and on the big stage like All Out (AEW's biggest show to date), the former Evolve star would pull out all the stops to come out victorious.
Allin has a date with Shawn Spears in his future, as The Chairman took the spotlight from Darby at Fyter Fest, but given he'll be engaged with Cody in Chicago, this is the next best option.
Both men are fantastic performers in their own separate way, and if given 15 minutes to open the show at All Out, they can both solidify themselves as future stars and potential World Champions in All Elite Wrestling.
