What we are saying is this is not anything new. They have been doing graduation year. how will it change anything? The players that know what they are doing have been playing on teams that match their graduation year. I don't see where anything is changing. Both organizations and college scouts have been encouraging players to play on their graduation year teams but allowed guys to play down if they fit the age part. If you look at the WWBA it has the graduation year for 17U as 2021. What answer are you looking for? A 17 year old should be playing on a 2021 team and a 16 year old who is graduating next year should be playing on a 2021 team. But if a 14 year old is good enough they can still play on a 2021 team. Nothing has changed. It just may say 2022 WWBA next year rather than 17U/2022 WWBA. coaches are not impressed when you play with your down rather than play with your graduation year. They assume you do not think you are good enough to play against your graduating competition.
If you have 2022 kids on your 15U team then they should be playing on an older team so the answer is yes. Your team will need to split.
