My issue with Zucker is that he's a fine grunt work third wheel for a scoring line, but I don't know that A. he can stay healthy enough to be of use over the course of the season, and B. whether Geno and Rust (or Rakell when Sully reunites GCR 18 minutes into the season) have the firepower to overcome a pretty meh guy production-wise on the other wing.
I think the best avenue (I say best while wincing, because yeesh) is Heinen-Geno-Rust with a Zucker-Carter-Kap third line. I don't love either line, or even really like them, but keeping Zucker on the third line may keep him more healthy and I'm not sure there's much difference between Heinen and Zucker when it comes to the impact/production of 2LW.
