He fought for...something
"One of the things about football is that there is always another team you have to defeat. War is permanent. This is the central fact of the game. You want a guy who always fights because you always have to fight. Who does he have to fight? The other guy, naturally--it doesn't matter exactly who.

But in life? When you're fighting with guns and bombs? Well, it kind of matters who you're fighting; one ought to know who the enemy is--at the very least. But does anyone know whom Pat Tillman was actually fighting when he was killed? Not according to the news reports. As far as I could tell from most of the breathless paeans that appeared last weekend, the former Arizona State star died protecting our freedom from--a bunch of unidentified guys."
