There were a couple of interesting Cards-related tidbits in this article in the Athletic:
This at first seems to be an admirable attitude, yet it precluded Arians from recognizing that, regardless of who's fault it is, his Special Teams Coordinator wasn't getting it done and needed to be replaced. If a player isn't getting the job done, you coach him up as much as you can, but if it's still not working, you've gotta replace him... why should it be different with an assistant coach? Ultimately, it's just arrogant to refuse to admit that a guy isn't good at his job and your efforts to make sure he gets better aren't working... that you chose the wrong guy for the job and now you need to find someone better.Arians is a rarity in that he never fired or demoted an assistant. For two years early in his career, he worked as a running backs coach for Bear Bryant at Alabama. In 38 years as a head coach, Bryant never fired an assistant, Arians says.
Arians: “That’s everything I don’t believe in. As long as your conduct is good and you work your a– off, my job is to make sure you get better. If you’re going to fire someone, fire me.”
...daveOne Super Bowl his team didn’t play in still bothers him. Arians coached the Cardinals to a 13-3 record in 2015, but in the NFC Championship Game at Carolina, they had seven turnovers and allowed Cam Newton to throw two touchdown passes and rush for two in a 49-15 loss.
Arians: “I was shocked how we played. I thought we were so ready to beat Carolina and we laid an egg. I’m still shocked. We had such a great week of prep. But I have no regrets about it.”
The year he thought he did his best coaching probably isn’t one anyone would guess. In 2017, his last year with the Cardinals, the team lost many to injury, including Palmer, running back David Johnson, Markus Golden, their leading sacker from the year before, and most of their offensive line. They still won four of their last six (including victories over 7-3 Jacksonville, 8-4 Tennessee and 9-6 Seattle) to finish 8-8.
