Yes, I was aware. And the situation isn't pretty. They're going to need to spend at least $3.5M on a LW for Malkin's line, whether that's by re-signing Jokinen or chasing another UFA. They're probably going to have to spend around the same on a 2nd pairing defenseman because there's no way they can rely on Scuderi in that role. Tack on another $3.0M to re-sign Sutter, and you're left with about $6M for 3 forwards and a defenseman. The problem with those numbers is that they are on the lower end of the spectrum.
CapGeek's payrolls for next season
do a pretty good job of showing why it's going to be such a challenge. The Pens have the third lowest "$/Opening" (based on a 23-man roster)
in the league at $1.78M per opening (9 spots); only the Blackhawks (~$1.25M per opening, 3 spots) and the Flyers (~$1.09M per opening, 6 spots) are lower. Now for the difficult part - there are 12 teams with over twice the "$/Opening" as the Pens, which includes some good teams like St Louis, Minnesota, Nashville, Ottawa, Colorado, Detroit, Phoenix, Anaheim, and Washington.
In other words, there are a lot of teams with a lot of money to throw at free agents. That means prices will be up, making it even harder for the Pens to fill their needs.
