The Penguins intend to wait a while before deciding if they’ll proceed with any significant discussions about an extension for defenseman Marcus Pettersson, relays David Pagnotta of The Fourth Period (Twitter link). The 28-year-old has become a key cog on Pittsburgh’s back end in recent years and is heading for a raise on his current price tag of just over $4.0.25MM. However, the Penguins need to determine if they’re going to be a team that’s vying for a playoff spot in the second half of the season or a possible seller if things aren’t going so well. If it’s the latter, they could decide the better move is to move him as a rental player at the trade deadline where there would be a strong market for his services. Accordingly, don’t expect a decision on that front for a while yet. Pettersson has four points in nine games so far this season while averaging over 21 minutes a night of playing time.
