I mean when you're looking at a 3rd/4th line role, Sturm fits that mold MUCH better. Sturm is a high energy player, great on the forecheck, ELITE penalty killer. He doesn't have that offensive upside that Eller does but I don't think Pitt is really looking for that right now. Also slightly better cap hit and the age is more of a factor for next year. You can reliably count on Sturm being the same player next year, whereas at 34 Eller could really drop off next year
I'll keep it real I really haven't watched Sturm enough to know what his fit would look like, however what I have watched of Eller on the 3rd line for the Pens would not be easily replaceable in terms of chemistry. The way him, Big Z, and O'Connor work together has made them into a line that can be trusted in all situations defensively and offensively. My fear would be you lose the offensive side when you add in Sturm. Additionally, you would lose Ellers presence in the locker room which he appears to be in a leadership role (in terms of pecking order probably 5th behind Sid, Geno, Tanger, and Karlsson).
As far as next year I even stated in my original Sturm is a few years younger, but isn't really a prospect level talent isn't really developing anymore, so what you have to look at is what is the likelihood someone like Eller falls off tremendously. Which given Eller's style of play (which isn't really physical and has never been the best skater on any team) I wouldn't expect him to fall off as rapidly as someone who posses that physical or speed game.
The slightly better cap hit you're looking at 450K difference which isn't even league minimum.
All of this I still feel like no need to make the move for Sturm at least with Eller as the piece returning to the Sharks.
The only possible move I see that would vastly improve Penguins situation is finding a way to not dress 77 night in and night out and addressing the 3rd pair defense.
