#1 Adam 'Hangman' Page
Ever since the announcement of AEW, the company have been positioning Hangman Page as a future World Champion, and with his main event battle with PAC at Double or Nothing coming up, he makes sense as #1. In terms of a main event star, Page has it all; the looks, the size, the athleticism, the gimmick and the charisma, and when you include his friendship with Cody and The Bucks, the case gets stronger.
Page is still in his mid to late 20's as well, so not only is he a star already, but he's the future of the company, and if he replicates his performance from All In, AEW will have a megastar on their hands. Chris Jericho is a big household name already, and he'll draw plenty of casual fans, but it's guys like Hangman Page that will keep them around, and right now, he's our prediction to be the first ever AEW Champion.
