Reps, Reps, Reps...
The biggest problem most of us face is that we don't really want to spend that much time practicing PATs. I don't like it! I don't even like the kicking part of the game LOL. But here's my two cents. Have your kicker practice kicking the ball without looking to see where it goes! Keeping his head down. Have him kick off a tee and then a block with a holder but watch his head and eyes and don't let him look up. I can't believe how much this helped my kickers. Kids always wanna see where the ball is going and they look up before they make contact, pulling their chest off and head up... striking the ball in the wrong spot.
