Norvell is going to be a tough get.
Full disclosure, I've spent my work weeks in Memphis for about the last 8 months. You'd think they were in the SEC. Tiger talk is all over the local terrestrial airwaves, local businesses have giant tigers in their parking lots, Memphis State apparel is everywhere and Norvell makes nearly continuous "celebrity appearances" all over Shelby County and evangelizes the program in a way that makes 2006 Greg Schiano look like Rich Kotite. He could run for governor and win.
All this, and he made $2.6 million last year. If he has a 2019 that's anything like his 2018, they'll pay more to keep him.
