The sad thing is, from what I've seen of fan reaction, that if Pioli stayed and made Bill Cowher or Marty Schottenheimer the HC or even gave them a role, a large majority of Chiefs fans would flock back and forget about it all.
Even on the Save Our Chiefs status update today, probably 8 out of 10 responses indicated that they want Marty as the GM! If they made him HC, people would come back. It's disheartening, really.
