Why does either team do this frankly?

Minnesota is cap strapped, Anaheim is not, Zegras is better offensively, Anaheim needs help scoring.

And Rossi is 5’9 and we all know what Pat thinks about that

We have five of our top 6 set for the balance of the decade: Cutter Gauthier and Trevor Zegras at LW, Leo Carlsson and Mason McTavish at C, and Troy Terry at RW. We shouldn't be trading any of them unless we get a replacement for him PLUS fill a hole somewhere else. And that will be virtually impossible unless another GM makes a mistake.

Exactly my thought. Not to mention Rossi is even less of a Verbeek player at 5’9 than Zegras.. by far
