Dennis Allen confirms that Mickey Loomis was not in favor of firing him after Panthers loss

Dennis Allen inherited a Saints team coming off 5 straight winning seasons.

Virtually no new coach steps into such a position. That's a pretty good hand! The only better situation I could envision in today's NFL involves either Andy Reid's health making him retire, or the Steelers (idiotically IMHO) firing Mike Tomlin. Bowles with the Bucs stepping in for Arians after the latter retired is the only similar new coach situation recently I can think of off the top of my head.
so nothing at all to do with the aging roster and cap situation and this minor issue of replacing drew brees that payton hit the eject button on... Dennis has done pretty well when he had a healthy squad. but dennis is a coach that needs an ideal situation and isn't alpha enough to command an organization when things get rough.
