Given their salary cap situation I am not entirely sure what the Pittsburgh Penguins can add at the NHL trade deadline. Given the way the team has played this season I am not even really sure what major need they might have or what trade they absolutely have to make. Maybe a backup goalie, but that is not something that is going to require a significant investment in trade capital.
They should still explore what is out there, because as we have seen over the first half of the season this team is still very much a Stanley Cup contender.
