Bringing back Rob Scuderi made perfect sense for the Penguins in a number of ways.

On the ice.

In the dressing room.

Almost everywhere, it seemed, except on the salary-cap spreadsheet.

No one disputed that the Penguins could use a reliable defensive defenseman. The issue was whether they could afford to give a 34-year-old a four-year contract with an annual cap hit of $3,375,000 to fill that role.

General manager Ray Shero and his staff, however, decided Scuderi was worth that investment -- and whatever financial repercussions came with it -- and Friday lured Scuderi back to the team he had left as a free agent four summers ago.

"It was a mistake to let Rob Scuderi go," Shero said. "To have a chance to have the do-over to bring Rob back is one thing I really wanted to do."

And so he did, although it's going to force Shero to make at least one more personnel change before the start of next season.

Especially after the Penguins and fourth-line forward Craig Adams subsequently worked out a two-year deal with a salary-cap hit of $700,000.

The Penguins have roughly $676,000 of salary-cap space available. Trouble is, they have extended about $1.9 million in qualifying offers to three additional players -- defenseman Robert Bortuzzo and forwards Harry Zolnierczyk and Dustin Jeffrey -- and that means they're guaranteed to exceed the cap ceiling of $64.3 million for the 2013-14.

That isn't a pressing concern, because NHL regulations allow clubs to exceed the cap ceiling by up to 10 percent in the offseason, but Shero will have to pare his major league roster before the games start.
"We have three months to get cap-compliant," he said.

"We have certain decisions to make."

He does not, however, have a deadline, other than the one imposed by the league, for doing so.
"We're not going to go too fast here, unless something presents itself that makes sense," Shero said.
It's not clear whether Adams' signing is the final one the Penguins will make, because Shero suggested he still was poking around the talent available on the free-agency list, but any deal they give out in coming days likely would involve a modest salary and a short-term commitment.
