Whatever the Pens do, it has to at least attempt to address our biggest roster weaknesses...hopefully without maxing out our cap with one move.
Marner is expensive as hell - cap hit and asset wise - and isn't the home run to address our needs he'd need to be to justify the price tag.
As I see it, the most attractive assets to target would be Nichushkin, Stamkos, and PLD. They all have warts, but that's why they're available. Nuke for absolutely everything he brings on the ice, relatively low cap hit, and neglible cost to acquire. Stamkos for what he'd bring in terms of goal scoring, playoff performance, the PP, and neglible cost to acquire. PLD for his size, snarl, ~30 goal/60 point production most years, youth, positional versatility, and the fact that we'd be able to send back a terrible signing or two like Graves.
Not seeing the juice being worth the squeeze with most of the other forward names floating around.
