Rakell and Karlsson is an upgrade on Batherson and Norris in the short term. Getting cleanly out of the Norris contract without retention would be a massive pro since they seem to want to go that direction. Rakell is clearly being sold high on, and Batherson is going to be the next Zibanejad late bloomer, but that isn't really the point.
It would be super easy to come here and post Batherson for Peterka and have everybody tell me what an awesome GM I would be.
Look at it this way, Jensen+3rd for Chychrun, 3rd+Joseph for future considerations, Hamonic playing 20 minutes a night, if I posted those in a speculation thread I'd get roasted, but those are a lot closer to the types of deals or returns I speculate about for our pieces.
