Because he is the coach and you aren't.
Turnovers/fumbles happen, they're part of the game. This kid is a beast returning kicks & punts. He has such explosiveness...but, does he need work? Yes, without a shadow of a doubt. But I was hoping he would show the guts to bounce back after the fact, and he did, taking the ball out of the end zone with a really solid return. That's enough for me. Work on the mistakes at practice.
