I don’t think we can compare the Hoffman and Karlsson trade to this really... although the return for Panarin won’t be at that 100% premium... its margin for difference won’t be off by much.
Panarin for Guentzel does favor the Pens by a lot. Obviously there needs to be a throw in or 2, which will even it out.
For that case, Dumolin and Brassard aren’t the answer. You’re eliminating their 3C need along with getting rid of arguably their best Dman. (pens homers say Letang out of sentimental value, then say point totals, but Letangs defense is god awful). I’d say Dumolin is their #2 option, but the most well-rounded player on their backend.
You would have to look at wings for this as a replacement. Take out the quantity with the throw ins for Murray added on to Panarin.
Something along the lines of:
Panarin
Guentzel, Rust, 2019 2nd
