I think the best comp for Gustavsson is Skinner in Edmonton. 3 years, a tad over 2.5.
Addison, I look to Pulock in 2018(cap was 4M less) and Boqvist last year. 2 year bridge should be a hair over 2M.
Greenway, if we were truly serious about forcing a trade now I would've expected a line-up alteration. I think it happens in the off-season. I can't help but look at Buffalo having 3 2nds, maybe a 4th if Johnson refuses to sign, lots of cap space, worse players expiring, and their prospects aren't ready(very solid group though). They should be all over Greenway for one of those 2nds. Maybe the deal extends a little, I could see Masters for a 4th as I can't see Iowa running 6 1st/2nd year AHL d-men next year, and Buffalo could really use a D prospect ready to play pro hockey. Maybe O'Rourke/Hunt for Johnson(refusing to sign) swap so they don't lose the years of progress and we can sign Johnson.
Goligoski, like Greenway, I don't see an in-season deal happening. We've been fortunate with the health of the 6 d-men, we won't be getting a better option as a 7th. I do wish we just kept Kulikov, but it is what it is. If Goligoski just wants to play, how about back to Arizona in the offseason? Dysin Mayo cleared waivers earlier this season and is owed 1.9M total over the 2 seasons after this one but is fully buriable, give them a pick swap for incentive(a 2nd for a 3rd) and they're ahead, getting a better player who might fetch a pick at the deadline and helps them hit the floor.
Hartman's a guy I'm honestly struggling to find a place I like now or next year, and I think Walker could play his role right now. I wouldn't be opposed to moving him now if we could get something that makes sense. Kravtsov? The Rangers could use a right hand shot forward and I can't see Kravtsov re-signing with the Rangers based on his time there. That's a gamble I'd take if it were there.
