The Tennessee Titans fired coach Brian Callahan on Monday, just six games into his second season. Callahan coached just 23 games, the same number as the last coach to be fired in-season, Ken Whisenhunt, and led the team to just four victories, one more than Whisenhunt. The timing of the move is notable in that it spares everyone the inevitable comparisons with former Titans coach Mike Vrabel, now the head coach of Tennessee's next opponent, the New England Patriots. Mike McCoy, who joined the team this year as a senior offensive assistant, has been named interim head coach for the rest of the season. McCoy has experience as an NFL head coach, offensive coordinator and more, but that résumé does not exactly inspire a lot of confidence for what is to come.
