For the NPYLL teams playing U15A for the Greene Turtle this weekend, are they mostly true rising 9th graders (9/1/99 - 8-31/00) or are some of those teams known to have more than a few holdbacks?

Not trying to make a point. Would just be curious for when evaluating the gameplay Saturday. Seems like the D1 kids that left my area for private school all got held back/ reclassified, but no holdbacks on our U15 team - rather a several rising 8th graders playing up.
