Just make to teams with the same large group of kids. Not hard. so have a U13 and a U15 teams and then have 2018,2019,2020 teams and so on?????????? Then read the rules of the tournament and put the correct team in the tournament. Your club should be running the same plays and styles on all there teams I would think so it should not be hard to do. And it would be great for the kids to great on one of the teams and avg. on the other.
