The NHL free agency period began on July 1. Many teams had the opportunity to scour the market and add some key players to their rosters for the upcoming season.However, some teams find it difficult to bring in new players and provide contract extensions due to their cap situation. Teams try to adjust their cap salary cap space after placing players on long-term injured reserves.When a player is designated as LTIR, his salary is temporarily excluded from the team's overall salary cap situation, allowing the team to make roster moves or sign a new player to replace the injured player.The amount of relief granted is equal to the injured player's cap hit, allowing the team to exceed the salary cap by the amount of the cap hit. With that in mind, here are five NHL teams with the most over the salary cap after LTIR adjustment.Five NHL teams are as follows:#5 Washington CapitalsAs per CapFriendly, the Washington Capitals are projected to have a cap hit of $84,200,834.The Capitals are currently $700,834 over the cap, which places them fifth in the league.#4 Vancouver CanucksThe Vancouver Canucks are projected with a negative $4,6267,917 cap space, per CapFriendly following the LTIR adjustments.The Canucks have placed two players on LTIR for a total cap hit of $5,750,000, placing them $1,482,083 over the cap space.#3 Florida PanthersAs per CapFriendly, the Florida Panthers are projected with a negative $1,175,001 in cap space.They have two players on LTIR with a cap hit of $11,000,000, taking them $9,824,99 over the cap space.#2 Pittsburgh PenguinsThe Pittsburgh Penguins rank second in the NHL in terms of the most over-the-cap space.
