I think that football has changed, it has become more complex. For example, it's faster, you have less free space, and you have to play from such small spaces.
Americans are analytical in their sports, which are very stop-start, so the numbers tend to add up. That's why Moneyball works for baseball. It doesn't work so well for football because it's a fluid game.
Football is not as easy as it looks from the television gantry.
Football doesn't depend just on your brain. It's not like on a computer. It depends on your body, too, and sometimes you are tired. Sometimes the opponent closes the space very well and marks you very well. Football depends on many things, not just on you.
For me there is so many factors in football, that's why it's the greatest team game. There are so many things that lead into having success, just like when you have a ton of success and when you have no success, it's not just you.
I've learned that football is a stupid sport for intelligent people because the simplest things are truly also the most difficult to get right.
Football is so difficult to predict.
You can play pickup basketball, but you can't really re-create football.
