The Pittsburgh Penguins could use a bit more defensive depth before the start of next season. This is especially the case when it comes to their left side, as they lost Ryan Shea to the Edmonton Oilers and traded Parker Wotherspoon to the Vegas Golden Knights. 

With it now being the middle of July, most of this year's top unrestricted free agent defensemen have been signed. However, there are some decent depth defensemen worth considering, and one of them is Mike Reilly. 

If the Penguins signed Reilly, he could compete for a spot on their bottom pairing. However, he also could be useful for the Penguins to have as their seventh defenseman for when injuries arise during the season. 

Reilly spent last season with the Carolina Hurricanes, where he recorded one goal, nine points, and a plus-11 rating. However, he also had six goals and 24 points in 59 games for the New York Islanders during the 2023-24 campaign.

Overall, on a cheap one-year deal, Reilly could be a decent depth pickup for the Penguins. He would give them another defenseman with a good amount of experience, which is never a bad thing. In 460 career NHL games over 12 seasons, he has recorded 19 goals, 114 assists, and 133 points.
