This is why lacrosse needs to follow USA hockey. Every team submits a certified roster to USA hockey for the season. For each game, a uniform score sheet (same form for all games) is used, with each team sticking its roster on the score sheet, which lists each player and jersey number. Each kid wears a jersey with their name on the back and the jersey number. Everything is open and transparent, and can be checked at HQ if need be. And a birth certificate is submitted with the rosters to USA hockey.
