I'd say the difference between Panarin and Huberdeau is big enough to pay 2+ million dollars additionally.
Poor wording from me originally. Sorry for that. I don't think that really is the question here.
Is Florida better team with a) Huberdeau + D or bottom-6 upgraded with the help of that 2+ million (or whatever the difference will be) or b) with Panarin? I don't think that trading Huby for Panarin helps Florida with team's bottom-6. Even if they divide talent to different lines.
Florida's top6, even top9 is in decent shape now. They have turned around within a year (after losing Smith/Marchessault) rather well since Dadonov proved to be great signing and then getting Hoffman. And there is more help coming from the pipeline. Borgström, Tippett are getting close. Heponiemi might make it with couple years etc. And that is added to Barkov, Huby, Dadonov, Tro, Hoffman...
Without injuries they already have 5 players who can score 60+ points. But they need help to bottom-6 and defense. Last year for Florida Pysyk was played over his head as #4D. He struggled. The bottom-6 wasn't good enough which lead to top-6 playing too much and becoming clearly tired towards the end of the season. I mean both Barkov and Trocheck had average ice time over 21 minutes per game. Barkov played #1D sort of minutes at some nights reaching that 27-28 minutes territory of ice time. Huby's scoring went down etc.
I think they need more upgrade to bottom-6/D than they need to upgrade Huberdeau.
And of course there is Tallon and his love for "his own boys". I don't think Huby is likely to move.
