Digging deep enough to try to really understand what has gone wrong with the Chargers might not unearth enough evidence solely contained in this season to support a decision to fire Mike McCoy.
But such mining would be trying too hard.
Right on the surface are ample reasons why the Chargers must change head coaches.
Whether the Chargers are playing here or in Los Angeles, McCoy is a liability externally and a luxury internally.
Anger – and worse, apathy — among fans. Ambivalence among players.
There is a cry from fans that can't be ignored and a lack of a cry from players that can't be ignored.
