They are a great team and would still be great if their HANDFUL of 4th graders were actually playing in their correct grade. But the question is would they be as dominant? The answer is no.
I am surprised that 91 director doesn't step in and put kids in their correct group.
Bottom line is if you have a 2022 kid or a few 2022 kids you should not be playing in a tournament against 2023/2024 kids.
