 This caused offers to restricted free agents to be rare to avoid ill will amongst general managers; there were no offer sheets made in the six years prior to the lockout.Beginning with the 2005 NHL Collective Bargaining Agreement, the NHL assigned a salary cap ceiling and floor for each season, so teams must spend money more wisely.This means it is more likely that general managers will offer a contract to a younger player with potential that their team does not see as much value in matching, rather saving money for other players.
