Awesome stuff. I think it shows that the most important skills for a QB are: (1) Ability to read and understand a defense, and to know what the right play is, and (2) throwing an accurate ball. It's not that arm strength and foot speed are unimportant or unhelpful. But if you have (1) and (2) above, you can be very very successful in the NFL. And Brady obviously has both in spades.
