Between Ralph, Russ, and Marrone (then Rex) we had the Three Stooges, only not as funny.
You can't blame Whaley for leaving the Steelers and taking the chance at being an NFL GM. There are only 32 of those positions, and they come available rarely. You have to take that chance, like a promotion you're not sure you can do at work. Stay where you are, be and do the same, or aspire for something better?
