I'd say that 1 player being demoted is almost certain, with 2 (and Keane getting upgraded) a possibility.There has to be players getting demoted to the rookie list or a player getting traded.
Smith, Strachan and Schoenberg obvious options. There'd be no interest across the comp for any of them so could delist comfortably.
The chances of Smith, Strachan or Schoenberg being delisted (and not re-drafted in the RD) are vanishingly remote.
Note that my previous post, which you quoted, is clearly marked as "confirmed (papers lodged)" list changes. I haven't included ANB & Peatling, who have nominated the AFC, but whose trade papers have not yet been lodged. Nor have I speculated on which player(s) may be demoted to the rookie list. It is confirmed changes only.
