Anyone who has played the game professionally you're always taught that the ball is the most important most precious thing so when the ball hits the ground it's always a mad scramble. It's amazing how many times there is a fumble and the person who recovers it initially doesn't walk away with the ball.
The military is a very cool world to write about. I went down to Ft. Benning Ga. for military training and I learned a lot about soldiers and officers and why they joined up and what their life has been like.
