Zucker and McGinn have negative value, and Poulin is maximum a middle six prospect, probably a 3LW at best, he’s definitely regressed since his draft. I don’t think this would even work without the two cap dumps, because there’s no blue chip prospect going to the Flames and the two 1sts will likely be late.

I disagree about the Zucker analysis. If healthy he's a top 6F.
I do agree that the prospects are both likely middle six and the picks are late. The problem is that Calgary can't win ANY trade. No one is going to give established young, controllable players. The best they'll get is prospects (blue chip or not the hit rate in the NHL is poor) and low 1st round draft picks.
Again, I don't think this is super realistic. Just the best the Pens could do.
