Quoting: Billy12Bob
According to this site PIT have $29 million to spend next season but are 11 players short of a full roster. Several of the players that need to be resigned are expensive.
I rounded up to $30M based on the rumor that they're going to give a small bump to the cap this summer, raising it to $82.5M.
It's hard to tell what the Penguins do next season, and I'd defer more to the Pens fans on this site, but my read is that if they DO re-sign Malkin & Letang it's probably for a similar cap hit. Rust is probably gone because he's going to get offered more money elsewhere; Kapanen and his $3.2M are probably getting traded or being allowed to walk because of his lack of production. Maybe Evan Rodrigues gets a bump up because of his early season play? The rest of the guys are bottom 6/bottom pair guys that they can promote from within/find decent UFAs for similar costs.
Point is, I think that they aren't going to be in a cap crunch next season. Even if you pencil in Malkin & Letang coming back for $18M combined(higher than I think they will), that still gives them $12M to fill out their bottom 6, get a 7th D, and sign a backup goalie. Gotta assume 1-2 guys on ELCs come up, meaning you probably can average about $1.75-2M per player and fill out the roster without going over the cap.
Lastly, even if they splurge somewhere and need to move a guy, I'd count Brian Dumoulin, Jason Zucker, and Mike Matheson as guys that potentially get moved before they get to Pettersson. Again, put yourself in Ron Hextall's place - if you're going to just try and offload a guy for cap purposes, who do you look at first - the over-30 guys with only a year of term left, or the 25 year old signed for 3 more seasons?
