Earlier this year the NHL announced that they expected that the salary cap could rise substantially this summer. The league was reporting record highs and felt like the players could see their portion of the escrow completely paid back. This change gave a lot of hope to teams who were struggling against the cap.
With almost half the league being within a couple million dollars of the salary cap this could lead to some big issues this summer. This could have a major impact on teams like the Colorado Avalanche, who signed Nathan MacKinnon to a major contract with the expectation that they cap would rise approximately $4,000,000 next year.
