My guess would be because he doesn’t give two craps what any of the fans think about any of his decisions.
And that’s how it should be.
Football isn’t a democracy.
Allen is paid to coach the Saints - we are not. If he doesn’t succeed this year, he will more than likely be gone.
How he does his job isn’t up for discussion and vote with the fans. He doesn’t need your approval and clearly he doesn’t seek it either - which really seems to bother a lot of people on this board.
If you don’t like Allen - don’t watch. Don’t go to the games. Otherwise, control the things you can and stop looking for reasons to get angry.
