Let me expand on Kevin's point about knowing a team's tendencies and how it can help you.
The high school team that I shoot most often has a 'Hail Mary' play designed to get a last second desperation touchdown. Most teams have such a play. Because I have an excellent relationship with the coach and try to be helpful to the program, he lets me shoot anywhere, anytime. This includes practice and the locker room before the game, halftime, and post game. He also tells me if a trick play is planned and the details of who, when, and where the play will be used. Back to the 'Hail Mary' pass. Because of the positive relationship with the coach, I know which side of the field the pass will be thrown to, the planned deception and who the eventual intended receiver will be. It doesn't matter who the ends are or what the wind is doing. That play will be run in a specific manner by that team. It's what they practice, what the coach believes in, and what they will do this year.
That's nice to know! I will be in position to shoot that potential game winning pass and be focused on the correct player. Guaranteed.
