The Pittsburgh Penguins have had a pretty active this off-season, as they have brought in new some players and lost others. 

When looking at the Penguins' current roster, it is clear that they should not be done making moves yet. One specific area that they should be looking to improve this summer is the left side of their defense. 

The Penguins traded Parker Wotherspoon to the Vegas Golden Knights and lost Ryan Shea to the Edmonton Oilers in free agency this summer. With this, it is clear that they could use another left-shot defenseman before the new season is here.

A few left-shot defensemen who are still on the free agent market include Logan Stanley, Carson Soucy, Mike Reilly, and former Penguin Matt Grzelcyk. While none of these players would necessarily be major additions, signing one of them would help Pittsburgh's depth. 

There are also some left-shot defensemen who have come up in the rumor mill this summer as trade candidate. Morgan Rielly, Alexander Nikishin, and Mason Lohrei are a few examples. 

It will be interesting to see if the Penguins bring in another left-shot defenseman this summer, but it is something that they should consider after losing two solid blueliners in Shea and Wotherspoon.
