severson's contract is up one year later, same for graves and siegenthaler. won't they ask for a raise or have to be replaced by better players to be competitive? or do you expect to replace them all with elc's?
ty comes off his elc the same year. bridge or long term? either way you can add at least 3m additional cap to the defense.
obviously you can assign cap space in very different variations to the positions. the devils only have two long term contracts (nico and dougie) and therefore plenty of flexibility. a full roster has 23 contracts (13/14 forwards, 7/8 defensemen, 2 goalies). equally distributed that's about 3.5m per contract. i wouldn't assign more than 28.5m (35%) to the defense, in the devils' case maybe even less, as we hope some of the first round picks at the forward position garner substantially more than the average.
if we assume a 7 man d-core, you should assign 4.5 - 5m for the bottom 3 defensemen. elc's could save you a few dollars for some time, but defenseman often take their full elc years for development. dougie at 9m is a given. let's assume severson resign at 5m, ty gets a 4.5m bridge deal and hampus replaces graves in the top 4.
9,0m dougie
x,xm hampus
5,0m severson
4,5m ty smith
4.5m bottom three
------------------------
28.5m total
if you go on the high side with 28.5m for your d, you have only 5.5m for lindholm. it most likely isn't enough and i wouldn't compromise in other areas unless the devils have some of their forwards and/or severson/smith on cheap mid to long term contracts.
