There's a serious flaw with this theory.
This season, including the last few weeks, the fans have cheered good plays. Even when they are down 10+ points, the fans have cheered and supported the team for every 1st down and score. You are acting like the fans have been booing from the opening kickoff and have sat on their hands whenever the Chiefs made a good play, and then that abruptly changed this week. That is not true. There's really been no difference this week except the absence of a banner flying over the stadium before kickoff.
If Quinn had thrown 3 picks or something like that yesterday, I guarantee you would have heard boos, shooting or no shooting.
