I would not be opposed to either of those trades, I just don't see them happening. I can't see clubs taking a 10 pick downgrade on their first round picks for players in their 30's with queries on their fitness.Higgins for a second rd pick.
Minson + pick 27... for pick 15 + Smedts (Geelong).
Cooney + pick 28... for pick 16
It would give us picks 5, 15, 16, 45, etc. Plus Smedts on our list.
Also I personally have no issue going backwards next season if it leaves us in a better position long term. I guess it is up to the club to determine whether trading out senior players would do that or do the opposite.
