Here's the last "first time coaches" hired from 2020 - 2023.
(2020) Joe Judge, Matt Rhule, Kevin Stefanski, (2021) David Culley, Urban Meyer, Robert Saleh, Nick Sirianni, Arthur Smith, Brandon Staley, (2022) Brian Daboll, Matt Eberflus, Nathanial Hackett, Mike McDaniel, Kevin O'Connell, (2023) Jonathan Gannon, Shane Steichen, Demaco Ryans.
17 "new" hires. 6 are already gone. 2 more on the way. Sometimes you get 3 years to show something. Sometimes less. I think Meyer and Rhule have proven college coaches aren't a good hire any more. Staley might have proven you need more than 1 year as a coordinator....if nothing else, to prove you can do it multiple years. But owners love the hot coach!! Quick success can occur though. Stefanski went to the postseason in year one but is just 23-24 since. How long does he hang around?
