You never know - he might have blown a lot of the money. He told the NCAA he has a "cash-driven lifestyle" during the hearing about his violations, whatever that means.
According to this page (
Tennessee Coach Jeremy Pruitt Salary - USA TODAY), Pruitt made approximately $17.4 million since 2010. Particularly since 2013, he's been in a high tax bracket, so let's say the tax man has taken about 30% of that income overall. That gets him down to $12.1m, spread over 11 years. That's a very nice income, but when you think about it in that way, it isn't as much as it sounds. It certainly is an amount of money you could blow if your spending was out of control. He's also got 4 kids.
I figured he'd go the NFL analyst route again like he did in 2021, but I think he might have only gotten that job because he was buddies with guys who were buddies with Joe Judge (Freddie Kitchens, Kevin Sherrer, Craig Fitzgerald, etc.). Given he's effectively blackballed from coaching in college, being a PE teacher might be the best job the dude can get right now.
