All players on a WHL team's roster are required to be on the 50 Player Protected List, so if a WHL team is carrying 23 players, this leaves only 27 spots available for future prospects. Needless to say, only the elite players will be represented on a team's List. If a player on the List no longer meets the expectations of the team, he will be replaced by another prospect. As a result, the List is constantly changing as teams evaluate their players and make adjustments. Teams are permitted to make changes to their 50 Player List throughout the entire year.
