My son started to play goal at age 6. He was great at Initiation(5-6 year olds) and Novice(7-8) levels with a butterfly style of goaltending. In fact, his team only lost a couple of games each year. Now he is an Atom (9-11) and still likes to go down into the butterfly real early. He's still doing ok but gets beat up high a lot. His glove and blocker are OK but not great. I have tried to teach him not to commit to early but to no avail. This down early into the butterfly style has worked so well for him so far that he doesn't want to change. He seems to do OK in the first period of games until the coaches of the opposing teams figure him out - they always seem to score a lot more goals in the 2nd and 3rd periods. How can I convince him to change his style? I have played a lot of hockey myself but never as a goalie.
