Rumblings: Are Penguins done making moves?

The Penguins made a big move by acquiring winger David Perron from the Edmonton Oilers earlier this month and he’s looked terrific since going to Pittsburgh.

Are the Pens done?

Maybe, maybe not.

"We’ll have a better idea once we get [Patric] Hornqvist and [Blake] Comeau back [from injury] so that we balance out our lines and get a better picture of what we got," Penguins GM Jim Rutherford told ESPN.com Tuesday. "But you’re always willing to listen and willing to make your team better."

Having said that, the Pens are tight against the salary cap, so any deal is likely dollar for dollar, which makes things harder.

In a perfect world, I suspect the Pens would like to further add a fourth-line forward to strengthen that unit.
