Should be U based and switch to grade based for rising 9th summer. Ultimately hold backs get mixed in with non holdbacks but at least it wouldn't happen until much later on
Most teams are formed for the combined Fall/Spring/Summer season (Fall 2015 Summer 2016 - is the same team). You can't change in the summer without also changing in the preceding fall. It is simply too messy for the club directors. This implies that the upcoming fall travel season is when you should see for the first time 2019s who are repeating 8th grade and are now 2020s. Since the 2015 summer season has ended even though your kid has not started 8th grade, unless he plans on reclassing you should start thinking of him on the club/recruiting circuit as a rising 9th grader right now.
The first 2020 will verbally commit well less than a year from now.
U-15 allows 2019 reclasses and 2020s to play together on the same team. Call it U-15 or call it 2020, it is the same thing.
