I'm not sure the Ducks would bite. That said, we are taking the bigger risk. Ritchie is a hold-out. That's not good. Perlini could explode and be a big time goal scorer. Ritchie is much more likely to be 15-20g per year and not much higher at any point. That said, he's behind only Ryan Reaves and Tom Wilson for hits by forwards over the last two full NHL seasons. And he's not getting anywhere near the PP time over the last two years that Perlini has (something like 30second/gp for Ritchie and 1:45/gp for Perlini).
It sort of lines up with our deals involving other young, talented players. We tend to move upside for safety. Ducliar for Panik is obviously upside for steadiness. Domi was slumping and kind of all over the place in terms of upside, and is a real wild-card. Galchenyuk, though with his own warts, is a bit more proven and a safer bet to at least be a consistent 20ish goal goal year in and year out.
We probably wouldn't be willing to take a risk like that in the division. Moving Perlini to the Ducks only to see him transform into a 25-30g guy is too much to handle, probably. Also, from the Ducks side, do they really want to deal with a pissed off, and highly motivated to run around Ritchie in the division? I'm sure they'd hate to see him crushing their guys six times a year.
