Jim Harbaugh is crazy.
"He is crazy, but he's a good crazy," Willis told ESPN Radio (via ProFootballTalk.com). "He's the kind of crazy that there is not a player on that team that would not go to war with him. And when I say 'Go to war with him,' I mean, he's crazy -- but most people would say, 'How could somebody be crazy but it's good?'
"He's crazy in that if he had to lay himself on the line to make sure that you'd live, the guy beside him would keep fighting, he would do that. That's crazy, but he's that type of coach for us and he has that with us."
