After the acquisition of defenseman Mike Matheson and the re-signing of Juuso Riikola recently, the Pittsburgh Penguins have too many left handed defensemen when added to the group that includes Brian Dumoulin and Marcus Pettersson.
Penguins coach Mike Sullivan is very much in-line with the strategies of the day, which includes playing left handed shots on the left side and right handed defenseman on their strong side on the right side.
The Pens have a problem there, since only Kris Letang and John Marino are sure-fire RHD players right now.
