Spend hours with the kid. In the classroom and film room. At home, watching videos of defenses and drinking beers. It was going to be this way when the Chargers were said to be drafting Michael Vick. Now that Vick isn't going to be a Charger, the quarterback the team did draft, Drew Brees, is supposed to assume the student position and bring Flutie an apple every day, just to get on Flutie's good side.
Quarterbacks have enough problems.
Not to say the kids don't get a helping hand now and then, but it's mostly learning through osmosis. This is all right, this isn't. You pick up clock management, how to run a two-minute offense. The veteran gives out helpful hints. It's not like you're sitting down with your teacher after class.
