Kids that are born in the earlier part of the year will be 19 in their freshman lax year at college. Doing one pg year is not that big of a deal. If he had repeated 8th grade, than chose a pg year- and was 21 at time of freshman year- that is something to talk about. I suspect, you will see some of the 8th grade holdbacks being asked to pg in the future as well. Will be interesting to see if they want to give up ANOTHER year of their life at that point. It will certainly be a much longer road for these kids to get to college. I suspect- some will be burnt out from an extra two years of schooling before they even start their freshman classes.
