Whoever used the two year system ..In NPYLL the AA was generally for the best teams..It had a lot of second year players at that age .less skilled teams and any teams with a bunch of first year players at that age played A. Could have easily been U15, U14,U13,U12. etc...Instead Crabs and others decided to go grade base to accommodate the private school holdbacks..Crabs know that they are going to get a bunch of holdbacks if not majority in Balt. Crabs have a good lax reputation especially at Private schools... ....
With the explosion of Club teams thus played perfectly into the Crabs,,They get the holdbacks....thus better teams.
