2020's are in high school now so reclassification should not even be on the table for discussion. One year makes a big difference in the middle school years. One year does not make a big difference in high school. Get over it or change sports if your kid is not able to compete at the high school level, but stop dogging the kids who are doing well. Your kid should find whatever he is good at and pursue it with a passion instead of the two of you tearing others down to try to minimize his inadequacies on the lacrosse field.
