Well, I might as well make these proposals here...............
Miller @ 50% to Washintgon for Hendrix Lapierre + Washington's 2022 -1st + Vincent Iorio + Winnipeg's 2022-2nd
Miller to Washington................for Hendrix Lapierre + Vincent Iorio + Winnipeg's 2022-2nd
--------------------
Horvat to Detroit.......................for Filip Hronek + Detroit's 2022-1st + Detroit's 2022-2nd
Horvat To Columbus.................for Chicago's 2022-1st + Corson Cleulemans/Kent Johnson
---------------------
Boeser/Garland to LA...............................for LA's 2022-1st + Durzi/Spencer/Faber
---------------------
Canucks want cap space, I dont think they are interested in retaining 50% on Miller and getting with 2.6 Mil dead cap next year.
I dont think they need to do that either unless it significantly ups the return which in your proposal it does not with only a 1st 2nd Lapierre, Iorio.
If they wait until off-season then there will be plenty of teams that can afford Miller at 5.2 mil.
Other trade's seem spot on, except i dont see DEtroit trading away a lottery pick for Horvat. Maybe though if they feel he is a centre piece of their core along with Seider
