Gundy was standing up for his kids against unfair judgment from the press. I imagine that whatever political side we're on, we feel that the press is unfair to our side. We'll all be able to give examples, and I think we'd all be right. This is not an invitation to go there, but a neutral statement saying, let's don't.
Much more importantly, apart from that, I like the standing up for his peeps part. I like the idea of taking the responsibility for what happens to his team, and shifting it away from his kids. Not all coaches or presidents or, in my world, dept chairs or deans, are MAN (or WOMAN) enough to do that. But it's what makes a good leader in my book. Are you responsible for your own team and accept the blame when things don't go well OR do you blame your subordinates (or players or those who work for you) for problems that come up, simply because you can dump on them?
For me this is why Gundy's rant was really admirable. He told the press to come after him, and leave his kids alone. Damn straight. I like that guy, despite the fact that he's coach of the Pokes.
