I don’t think there are any college coaches considered for a NFL HC job right now. Lincoln Riley was at one time talked about but not anymore. There was an article somewhere about this in the last few months and how it’s not really a pool looked at so much anymore.
Urban Meyer failed spectacularly. Even Saban, didn’t work out all those years ago. Unless you’re like Harbaugh with an extensive and a successful background in the NFL, it’s not likely. I can’t think of any coaches like that in college right now.
