I thought the policy was that you have to play at least three tourneys with the WS roster….unless I understood wrong.
“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.”
So essentially a player’s first time ever playing with a team could have been at the qualifiers.
In my opinion, rosters should be finalized immediately after the fall tournament season, when coaches had time to evaluate and make any necessary player and team chemistry adjustments.
