I think people put far too much emphasis on championships, Warren Moon is one of the greatest QB's I've ever seen in my lifetime, but because the Houston Oilers as a team were either marginal or butt most of his career he never gets mentioned. A lot of guys who played in eras either before free agency or pre salary cap (which prompted a lot of players to jump to teams more willing/able to pay them more) get boned because they played for bad teams.
Also I hope this is a lesson learned for TK that AEW isn't built to come right off a PPV and then build for another one within a month.
