No, there is an internal unique number (PNum) for all players. Any information that you change about a player will have no affect on the statistical records stored for him. You may change his name, the Jersey number, or his primary position. All reports will reflect the latest information. WARNING: If a player leaves the team and had game statistics, changing his name and information to a new player who takes his place will assign all the older player’s stats to the new player. In this situation, inactivate the first player and then add the new player. You will then be able to reassign the prior player’s jersey number.
