FLAGSTAFF, Ariz. (AP) -- Ray Horton has superior credentials to prove what kind of man he is.
This is, after all, the guy who just before leaving the Pittsburgh Steelers coaching staff gave his Mercedes to a cafeteria worker.
Correct that. He sold the car for $20.
As he put it, "I'm not crazy."
He's also not always Mr. Nice Guy in his new job as defensive coordinator of the Arizona Cardinals.
As defensive tackle Darnell Dockett said, "Yeah, he's a nice guy -- until you mess up."
Horton is in a precarious job -- the third defensive coordinator in coach Ken Whisenhunt's five seasons in Arizona.
