Yes, George and CeeDee missed curfew. Oh, the horror.
It's not a narrative. It's common sense that a team's won/loss record depends on many different factors, and trying to marry the value of wide receivers who are at or near the top of the league in production to overall team failure is futile. Whether they are considered "headcases" or not.
There are many more examples of WRs who led the league in receiving on teams who "didn't win" than there are examples of ones who won the Super Bowl. See Ja'Marr Chase, Justin Jefferson, Tyreek Hill with Miami, Stephon Diggs with Buffalo, etc., etc., etc. In fact, there's only been ONE GUY in the past THIRTY years who led the NFL in receiving yards and also won the Super Bowl in the same season, since Jerry Rice did it in 1994 -- Cooper Kupp with the Rams in 2021.
So your own narrative saying that there is some correlation with the Steelers not winning while they had Antonio Brown because he was not "worth it" really means nothing at all.
