He always talks about being short on help, short on time, short on money. He obviously still loves winning. Why not just close the doors on your own operation and go drive for somebody? He wouldn't make near the money but he wouldn't have near as much crap to deal with. There probably isn't any top ride he couldn't get. Even Clint Bowyer ain't stupid enough not to hire him.
If "help" is his biggest problem, I can't imagine that it would be hard to find somebody drug free and reliable to work with one of the best ever. He could afford to pay them even $1500 a week if he had to in order to get somebody decent. Heck, call Jared Landers he's available. He has to know at least a little bit how to work on the car, and was never late.
