As a coach, at any level of the game, the last thing in the world you do is "quit". If you get fired, fine then you get fired. But you go down with the ship. You don't just quit and go looking for greener pastures. What kind of message does that send your players when you just say "I can't take it anymore. I quit. And oh, look, I got a job I like better." I'm sorry if you think there is a double-standard there, but to me, it's like night and day. You ride it out and you make the most of it and you try to use whatever you can as motivation. You try to find teaching points in losing. If you're gonna lose, at least learn from it. Use the adversity to strive to get better knowing things only will with time and patience. Yeah, this struck home with me because you never quit on your players no matter what's going on. If you wanna hang it up after the season, that's one thing. But what Petrino did was dispicable.
