The Pittsburgh Penguins already have picked up top-line winger David Perron and fourth-line center Maxim Lapierre, but they’re likely not done.

Word is the Pens could still add both a piece up front and on the back end -- or at least one of them.

Among the forwards Pittsburgh is keeping a close on these days are Toronto Maple Leafs teammates Daniel Winnik and Mike Santorelli. Both are pending unrestricted free agents headed out the door and both carry cheap cap hits, which is very important to a cap-tight team such as Pittsburgh.

Thing is, they’re hardly alone in eyeing one of those two players for just that reason. It’s believed the Leafs are asking for a second-round pick for each of those players, a fairly high price that some teams are balking at right now, but given the interest, they just might get it from somebody.

On defense, I think the Pens would like to add a bit more experience if they can swing it. Those on their radar include Cody Franson, Jeff Petry and, to a lesser degree, Scott Hannan and Jan Hejda.

If Marc Methot doesn’t re-sign with the Ottawa Senators, he’d be another guy to throw on the list, although the competition would be fierce for his services.
