The level of play at this age has changed greatly. Any teams that are not playing or practicing all year long are at a disadvantage. There is no team on the island who will wake up one day and be able to play with the dukes, crabs and looneys. The express play and practice every week. They are small compared to the other three teams. There is no teams on the island that will dominate these teams including the express.
Very few if any kids at this age have eliminated all other sports to just focus on lax year round. If they have, I think its a mistake. I'm sure in Maryland the crabs and looney kids also play other sports in the winter. Its only the lax club program directors that would endorse dropping all other sports so they can continue to collect more fees for meaningless off-season tournaments, clinics etc. Lets see what happens when basketball, wrestling etc.. is over.
