tbh I don't know. Some reports have 3-4 pieces for Miller others much less. Depends on the media source, e.g., TO seems to think we'd be happy with Liljegren or Holl and Kerfoot
I'd love that deal you proposed tho, it fits so many needs.
IMO if the 2nd is really in play, then we shouldn't expect multiple pieces back. I'd be satisfied with the 2nd and McLeod given how hard it is to move up into the top 3 and how rarely that really happens. I think many would be OK with a 1:1 swap, Miller for the 2nd.
I could see maybe 2023 lotto protected 1st, McLeod and Severson.
