If all these leagues and events required US Lacrosse registration there's be no effort to disguise anything. Kids would be registered with a USL ID number and birthdate would be on their registry.

How many years has it been since any Crabs sponsored tournament required USL registration? When people fight to keep things secretive and oblique there are always reasons for it. What privacy matters people have with birthdates is offset by a greater need for fairness. In soccer kids are registered with transparent birthdates. Little league doesn't list birthdates but to register for teams you have to be in a age limit bracket. Those are bigger sports than lacrosse. Lacrosse wants to hide in te shadows it seems.
