If the World Series truly dropped to US Lacrosse age requirements then absolutely, a Philly team can not only compete but they can win. Philadelphia youth lacrosse does not have nearly the amount of re-classed kids that the hotbeds have so there's a natural advantage there in that probably 85% of the kids on the Philly teams are going to be age appropriate and have played together for years as opposed to a thrown together team. Keep one thing in mind though, even though most Philly teams are age appropriate many of them have 2 or 3 kids with July and August birthdays so they will not be able to go.
