I long ago remember ice hockey players who did PG years. They were great hockey players usually from Canada who needed the academic finishing year to be able to go to a good US college. The PG year had absolutely nothing to do with being a year older once at college or looking better against younger players. A lot of those guys were expected to be NHL draft picks and had bigger fish to fry in their sport. If anything it was something remedial they didn't want to do but needed to do for the admissions office to take them on. Lacrosse is not like that. Lacrosse parents will spend hundreds of thousands to buy in.
