We need 3 forwards at minimum right now (4 if you count burying Condra, and 5 if you count a 13th [although one of those is likely to be Erne]), so that's going to eat some of that cap space. I think we need 3 Dmen signed (two of them are likely to be Koekkoek and Dotchin - possibly Sustr) + 1 more for a 7th. So I count, before re-signing anyone, 8 roster spots to fill with 23 million.
Erne is like 700k. Dotchin and KK will likely be around 1.1 or so. Call the three of them 3. 20 million to fill 5 spots. 11 million to Johnson and Palat. 9 to fill 3 spots. Burying Condra gives us 10 to fill 4 again (two dmen and two forwards - we'd like one top six and top 4 ideally). Say Sustr at 1.4 again. 8.6 for 3 spots. 900k to Gourde gives us 7.7 for 2 spots.
We're likely going to have trouble getting both a top 6 forward and top 4 dman with 7.7 in cap space. Our best bet is a guy like Marleau taking a cup-hunting/bonus heavy deal. Paying Shatty 6 though kills the dream of getting a top 6 forward as well. HOWEVER - if instead of getting Shatty in FA we get a guy like Nate Schmidt or CDH or even a Scandella, our universe opens up quite a bit.
Namestnikov - Stamkos - Kucherov
Palat - Johnson - Gourde
Killorn - Point - Callahan
Erne - Paquette - Brown
Dumont
We could probably use a 2RW to upgrade Gourde then put Gourde on the 3/4th line to improve the bottom 6, but that's 1 forward and not 3.
Hedman - Dotchin
Coburn - Stralman
Koekkoek - Sustr
Witkowski
We could upgrade on Coburn to move him to the bottom pair, but that pushes Koekkoek out. Or upgrade Sustr but a 3rd pair defender isn't much. They refused to trade or send Witkowski down last year in fear he would get claimed so would seem they want him back.
We don't really need anybody, give Gourde, Erne, Dotchin and Koekkoek the chance to impact the roster instead of bringing in someone to push them to the press box and kill their development.
