Their season isn't over until it's over. But I do think the Chiefs "mystique" is over.
KC had that thing that the Patriots had for years. Where teams would press when playing them and make mistakes to beat themselves.
Mahomes is still a good QB. But he hasn't been "Mahomes" for 3 seasons now. Kelce is showing his age. And the great defense, that was carrying them, has lost a step this year.
They call still retool next season, though, and be right back in it. Reid/Spags is an all-time great duo.
