When it comes to the possibility of an in-season coaching change, a team has two clear opportunities for processing the adjustment on the fly: (1) during the bye week; and (2) after the short-week Thursday game.
For the Chargers, the short-week Thursday game comes tonight. If the Chargers, who could be 5-0 if they could hold a lead, lose to the Broncos at home, it could be the last game Mike McCoy coaches for the team.
Ian Rapoport of NFL Media suggested on Sunday that McCoy is entering a critical two-game stretch, featuring AFC West games at Oakland and then on Thursday night at home against the Broncos. A potential win over the Raiders already has been squandered; a loss to the Broncos would drop San Diego to 1-5 with games at Atlanta and at Denver next on the docket.
With the bye not coming until after home games against Tennessee and Miami, it could be too late if the Chargers wait.
A half-measure is also possible. For example, defensive coordinator John Pagano could be the one who goes, if another lead is blown.
If McCoy goes, offensive coordinator Ken Whisenhunt possibly would acquire the whistle. A year ago, however, it was Whisenhunt who was abruptly fired during his second season with the Titans.
It all becomes moot if the Chargers win tonight. I personally think they will.
