With the Jarvis signing including deferred signing bonuses, the Canes have themselves set up cap wise to just about perfectly maximize LTIR when the time comes to do so.
An initial roster of:
Aho, Svech, Jarvis, Necas, KK, Martinook, Staal, Roslovic, Carrier, Drury, Robinson, Jost, Lemeiux (Fast IR),
Orlov, Slavin, Burns, Walker, Gostisbehere, Chatfield, Honka
Freddie, Kochetkov
Puts us at a cap hit of 87,981,754. Then Fast can be placed on LTIR and the Canes will effectively have almost the full $2.4 million in LTIR space to use later on if we choose.
I just used Honka above to maximize LTIR, he would not be on the team of course. There are multiple permutations the Canes could use and if we are willing to risk losing Jost or Lemieux via waivers, we actually can get even closer to $88 million in cap hit than my example before putting Fast on LTIR.
I don't expect the Canes to actually use Fast's LTIR space if we don't have to, but its good business to maximize the available LTIR at the beginning of the season just in case we do. Canes are set up to do so.
