Mikael Backlund
Last is Mikael Backlund. This is a player that the Pens most likely already looked into, but Backlund would be a perfect fit on this team. A player that can kill penalties, be a constant plus player, and con score 40-50 points a season is someone you should want on your team.
Backlund put up 53 points this season and was one of the Calgary Flames best players in the regular and post season adding 3 points in 4 games. He is a guy that would become so much better playing under a team with as much star power as the Penguins.
There are really no third line center options already in the Penguins organization right now. The best option would be Scott Wilson. But he should get another full year of hockey in before the team tests out that option. For now, making a trade is the best choice to go.
