Well it seems there are no real rules, off the field, in club lacrosse. My son is an August bday, 13 now, in 8th grade and a solid player on a 2022 team, where he is perpetually one of the youngest every year. My plan is to just put him on a 2023 team this spring, maybe even a 2024 team. If anyone asks us about his grade, we just lie and say we plan on downgrading next year for private school. I am 100% sure no coach will bat an eye. I do feel sorry for the unlucky 2023/24 on-age kid that he will replace. This is the wild west, you really can do whatever you want.
