Buyouts for Rust and Granlund line up pretty well with our remaining 2-3 years left of our core, and are dirt cheap during that time. Especially Rust, the much harder to move contract considering length and NTC. And then the Rust buyout helps you reach the floor and really suck out loud for a couple years when it's important we do so. For me, you have to get rid of Rust this offseason and let Zucker walk if you are going to remake this roster. You could risk it and start the season with Granlund on Geno's wing, with plans to dump him mid-season in the hopes you get his value to positive and replace him with Puus or a trade.
If a GM comes in who can actually leverage analytics, they should be able to find some bottom sixers who can play some defense and a 2nd pair LHD. This team already has the difficult slots filled, 1st line, 2C, 1st pair defense, right side defense. Same deal with goalies, a good analytics department should be able to find a couple of goalies to run in a tandem.
If given full authority, I'd love the Pens GM job right now, there's nothing but upside and it's within your control to create a ton of salary cap space.
