Much like in ice hockey, the players (including the goalie) are free to substitute on and off during the play always entering and exiting the court from the area near the half court line designated for substitutions. The new player cannot come on the court, however, until the departing player has exited the court entirely. Coming in too soon results in a 2 minute suspension. Many teams like to substitute 1 or 2 players for offensive/defensive purposes. These substitution patterns can easily be accomplished from defense to offense as the team on offense can slow play up a bit to make the substitution. The switch from offense to defense, however, cannot always be made because the time required for substituting could result in the offense having a man advantage.
