A lot of it is fatigue for many not wanting the Chiefs to win the Super Bowl again. And, when you are one of the best teams in the league that is playing more games than almost any team (playoffs included), and you are often in primetime, there will be a lot more focus on that team.
If you are talking specifically this year, I don't know if we've seen a top tier team get as many "breaks" as they have, but good teams make other teams pay when they get those chances.
Anyone who says the Worthy catch was not a catch just flat out does not understand the rules and is objectively wrong. It was clearly a catch. Now, the third down that was marked short was rough and then the stop on 4th down was VERY close. You almost had to go with the call on the field there.
