When he came back from his stage dive injury, the storyline with Moxley sucked. Then he injures himself AGAIN, the guy supposed to fight him next gets bigger cheers than him, he shyts on the company in the press conference, knocks out one of the EVPs in a fight that causes a suspension for one of AEW's biggest single stars. Not to mention his injury/drama basically throws off the main event booking for the rest of the year bc Tony Khan sucks at adapting.
He comes back again and instead of being a fire-breathing heel he is some lame ass version of 1997 Bret Hart, and gets involved with backstage drama again. The ratings for Collision have already tanked and the crowds are getting smaller and smaller in the building.
From his debut to the dumb stage dive injury he was probably at a solid 8/10, but everything from his return from that injury to now would be as close to a 1/10 as it gets, so I think an overall 5/10 feels fair
