I really like the top three lines you have, especially if JT brings a heavier game.
I am also all for moving out Kampf and Jarnkrok, but at this point (a) what do we do with the cap space, and (b) the fourth line you have without them doesn't really do anything for us and we lose two PKers.
Could we acquire a fourth liner in the process? Could we maybe use that line as a way to see the kids? Maybe a fourth line of Cowan, Minten, and Grebyenkin or Dewar every now and then?
I also worry about losing Murray on waivers and think we need to keep a spot and dollars in case we decide we have to break camp with three goalies.
I think you get a pretty solid energy 4th with Dewar and Lorentz (I like this player, often noticed him on Florida). Holmberg slots in anywhere in the bottom 6 without much fuss, I just like McMann's fit better on the 3rd line. Reaves will get his spot starts and hopefully keep up his play from the end of last season.
PK is tough. I was mindful of losing Kampf's faceoffs, but I think we make up for it elsewhere with this construction.
Our top PKing forwards would be Dewar, Lorentz, and Marner. There's some speed, grit and scoring touch there. The gamble is whether Matthews can continue to develop as a PKer and become a staple on the second unit. Then you have Nylander, McMann and Holmberg on spot duty.
It's not perfect up front. We won't start with possession as often. Though I think we will have better puck pursuit and a great counter attack.
Tanev and Hakanpaa (if healthy) will really elevate our kill. Benoit and McCabe are no slouches.
I struggle to see our prospects cracking the roster this season. If they do, it's more likely because of injuries or someone really not panning out (Robertson or Patches). I don't think the kids are totally kicking in the door yet, but they aren't far off.
Cap space can be used to fit Patches/Lorentz post PTO contracts. We'll need wiggle room for the TDL. We have some solid depth in the minors for injuries, including the aforementioned prospects. Maybe we pick up one more depth D?
