When you're Nick Saban, anything less than a National Championship just won't do. He is the most perfection-seeking person I've ever seen. Sometimes, I just don't understand why some people don't get the way he is. He want's to win.....ALWAYS. It is literally the reason the game is played; to score more points than your opponent. And I'll never understand why some players won't buy in to his system. It's not like he doesn't know what he's doing. If you, as a player, just listen to him and do what he says, it'll all work out in the end.
Yes, he's not perfect (nobody is), but that doesn't mean he can't get pissed when the record isn't perfect.
