Eligibility rules from WSYL website:
“ All players must compete with their team or program on a regular basis. Players cannot be added only to participate in the WSYL and teams cannot be formed out of a partnership or alliance between two or more standalone clubs. The intention of this rule is prevent the formation of all-star teams for the purpose of participating in the WSYL. At a minimum, players must compete with their team/program for at least two events (outside of a WSYL event), which can consist of tournaments and/or seasonal leagues. These events do not need to precede the qualifier but must precede the Championship event. ”
