My understanding is that although Miller was delisted in 2020 and then placed on the rookie list he was elevated back onto the senior list in 2023. And, to my knowledge, Seth Campbell is still on the rookie list. So your numbers are still correct. i.e. 34 on the senior list (including un-contracted Dow and Sonsie) plus four on the rookie A list (including Seth Campbell) and one on the rookie B list.
I think both Dow and Sonsie will be delisted leaving four senior list places and two rookie list places vacant. In the draft, use picks 3 & 4 on best available. If a bid comes in for Kellaway before 38 use it for him and if not, at pick 38 select best available (assuming it's not Kellaway). At this point trade pick 81 for last pick in the draft (just so we have something to match a bid on Kellaway post pick 38). If, subsequently, a bid comes in for Kellaway, use the late pick to match the bid but if no bids come for Kellaway use our last pick to elevate Seth Campbell making three places on our rookie list.
In the rookie draft, pick Kellaway at our first pick, find a VFL ruck (I think we are in loads of trouble if Nank goes down) and place Dow or Sonsie on the rookie list.
