Age is the players age on
of that season.
Grade TY/LY shows the highest level a player has played this year (TY) and the mandate level (LY).
Grade is the mandated level of the player. This is defined by adding age + class, so a grade 15 for
a 12 year old would mean the player is mandated to the Elite (3) level. Each team is allowed 4 players of
a LY grade one level higher. Upon adding the 5th player, the team will be moved up.
BC column represents if Nations has verified the birth certificate for a player matching the
full name and date of birth in the system for that player.
