Good for the individual but bad for the group. Been covered so many times before on the forums. Would be great if there was a standard date set by a governing body and all abided by it. 8/1 or 9/1 of every year would be my choice to line up with the school year but whatever date would be fine. High school and college multi year competition is a red herring. What matters is development time before high school and there is an obvious advantage to be older during that time period.
