The Pens are definitely protecting the following forwards: Sid, Geno, Kap, Rust, Jake and McCann.
The Pens are definitely protecting the following dmen: Dumoulin and Letang.
I believe they expose Carter because there's really no incentive or logical reasoning for Seattle to take Carter.
Zucker, ZAR and Tanev will be available and I think they either take Zucker or ZAR if they choose a forward.
I believe likely protect Pettersson, expose Matheson, but I won't be shocked if they protect either Riikola, Ruhwedel or Friedman which on the surface seems crazy and counterintuitive, but if they want to try and move salary off the books in a hurry, they will do it.
