Kingsbury has it figured out. He’s got a ton of money, found someone he “loves” (probably not, but you can use your imagination), and is relaxing away from the stress.
From a football standpoint, I don’t expect him to go back to the NFL. I could see him in college again where his charm works on the young and won’t wear on them as they are only there a few years. He doesn’t seem like he’s cut out for the NFL. If he wanted to try to coordinator route, he could. And if he did, this would be a good spot knowing the commitment is not long. If he’s successful, he can get another job. If he doesn’t like it, he’s probably getting fired anyway.
