Not having superstar center Evgeni Malkin and No. 1 defenseman Kris Letang in the lineup are huge losses for the Penguins.
But credit GM Ray Shero for building a roster with tremendous depth that can replace top-tier players and still win games against the best teams.
Malkin missed nine games during the streak, but returned for Thursday's win over the Winnipeg Jets. He has one goal and an assist in his two games back from injury.
With second line left-winger James Neal and third-line center Brandon Sutter struggling in Malkin's absence, Pascal Dupuis has stepped up his game.
Dupuis had six goals and two assists in the nine games that Malkin missed.
Crosby also had 14 points during Malkin's absence, which helped replace his offensive production quite a bit.
The Penguins' first line of Kunitz, Crosby and Dupuis was the best line in the NHL last month. And with Crosby now injured, Malkin will step in and lead the offense.
It's very possible that Neal, Malkin and Iginla will play together on the second line, which has the potential to be the best line in hockey.
As for Letang, he was injured on March 17 against the Bruins. He returned to the lineup on March 26 versus the Montreal Canadiens but picked up another injury and has missed the last two games.
There hasn't been a defenseman who has produced much offensively in Letang's absence, but that isn't a problem for the Penguins since the bulk of their scoring comes from the forwards.
Pittsburgh has tremendous scoring depth, which allows them to win without two of their three-best offensively skilled players. Seven Penguins players have tallied more than 20 points this season, which is quite impressive.
Now that Malkin is healthy and Shero has added Iginla and Morrow to the lineup, don't expect the Penguins offense to struggle despite the fact that Crosby, Letang and Paul Martin are out of the lineup due to injuries.
