a team can increase its cap room if it trades high-salary players to other teams and gets lower-paid players in their place. a team cannot trade its cap room to another team or defer its cap room to subsequent seasons. other practices once common in the nhl, such as exchanging cash for players or agreeing to pay a portion of a player's remaining salary after trading him, have been explicitly forbidden in the new cba to try to prevent wealthier teams from evading the restrictions of the cap.
