#1 Worst: Jon Moxley bullies a non-wrestler for a good while
The idea of a match between Mark Sterling, MJF's lawyer, and Jon Moxley ahead of the Jon Moxley vs. MJF match at AEW All Out was not a bad idea per se, but honestly speaking, it went on for far too long. It makes all the sense in the world for a heel like MJF to bully a babyface with no actual wrestling skills, but for Jon Moxley to actually toy around with a man who is supposedly not a wrestler did not really make sense for a good guy (or even a tweener).
The worst part about the match between Jon Moxley and 'Smart' Mark Sterling (is it a good idea to use insider terms in an International broadcast, where people outside the business may not exactly understand the joke?) is that it was in the main event spot. Yes, the same main-event spot where Cody Rhodes was pulverized by the Dark Order in a segment that is still being spoken about to this day.
