I'm not doubting his resume, he was a top tier coach when he coached but coaching vs TV is just a whole different animal when it comes to analyzing the game.
10 years is a long damn time, look at Jeff Fisher with the Rams 2 years ago. He was a good coach from that era as well. Game changes fast, and not everyone adapts like Bill Belichick or even Andy Reid.
Just their offseason alone has me thinking he's taking a very antiquated approach.
Beyond that, I just think that team is in a shitty situation in general. In a year, they're not even going to have a homefield in Vegas as that will become the vacation weekend for every visiting team's fan base.
