Patriots quarterback Tom Brady caused a stir recently when he lost his cool on the practice field and called his offensive line a bunch of fat cows. "Yeah, I know ? it wasn't my finest moment," Brady said. "I got a little heated, and I was surprised that came out of my mouth. Someone said to me later, 'Tom, did you really call us fat cows in the huddle?' I started laughing. But at the time, it wasn't funny." Brady has little patience for anything less than perfection. Especially as he enters the final year of his contract and attempts to make another run at a Super Bowl title. "It's just so hard to win," he says. "It doesn't just happen. As you get older, you realize that, and you try to convince the young guys. You've got to pay the price."
