4. Size Matters
While the Exalted One could've been anybody, really, someone with an imposing build works for this role.
Evil Uno may have a heavyweight frame, but he, Stu Grayson, Alex Reynolds, and John Silver are all on the shortish side.
Lee towers over them, and thus projects authority from a physical standpoint. AEW's finally amassing a solid collection of heavyweights, with Lance Archer coming in, Jake Hager activated, and Jeff Cobb possibly signing full-time down the road.
Putting a powerhouse like Lee in this prime spot adds weight to the role.
