The Rasmus situation will probably fall somewhere with the range of the other returns we've had in Lindholm, Hanifin and Markstrom. It is feeling very Hanifin-esque though.
All those returns included a 1st + a worse roster player with some potential.
The roster player quality varied from Miromanov < Kuzmenko < Bahl.
Then obviously the lindholm deal had alot of addons.
Using these previous deals as frameworks:
Stars:
Bad deal (Hanifin equivalent): 2027 1st + Oscar Back
Better deal (Lindholm equivalent): 2027 1st + Bourque/Bischel + Dumba + 2nd
Golden Knights:
Bad deal (Hanifin equivalent): 2027 1st + Schwindt (

)/Holtz?(feels like with Holtz this wouldn't be terrible)
Better deal (Lindholm equivalent): 2027 1st + Connelly/Ihs-Wozniak + Lauzon + Cataford
