I'm of the mindset that the Pens should not go get a top line winger (Bobby Ryan, Rick Nash, etc.) to just get a top line winger. That is when you overspend. With Pittsburgh's lineup, a top line forward is just not necessary. Obviously with Zach Parise it was a different story. He was friends with Crosby, an UFA, and Captain of the Stanley Cup runner ups. But once we lost out on him, we have more important deficits to address before a top line winger. Obviously there is an opening on the top line with Crosby, but that can be filled by bringing up Kennedy (or another player) or signing a cheaper UFA player that can fill that role (Wellwood? Knuble is too old and couldn't fill that role in Washington this season).
Last season the Penguins outscored the entire NHL. The Penguins had 282 goals and the next closest team was the Bruins at 269. This was all without Crosby for the majority of the season (60 games). In the playoffs, the team scored an average of 4 goals a game.
What the Penguins lacked was defense and bottom line forwards/character. Getting Taylor Glass was a start and bringing up Dustin Jeffrey will help, but the Penguins need more grit and character. On defense, the Penguins have Orpik and then no other solid defenseman that can shut down the opposing team. Do you trust Martin to fill that role? Lovejoy? Nisky? Engelland? Scott Hannan could be a solid older pickup, or the team could look to fill this area with a trade.
