Prefer the following.
Richmond:
Out - picks 14 & 32
In - Motlop & Yarran
Carlton:
Out - Yarran & Henderson
In - picks 12 & 28
Geelong:
Out - Picks 12 ontraded 28 Motlop
In - Henderson & 14
Everyone wins IMO
I can't see Carlton accepting 12 and 28 for Yarran and Henderson. I think Carlton probably want something more like two late first rounders, maybe something like 12 and 20 would be acceptable but 28 is too low in a weak draft. Carlton pass IMO. They need more. Carlton may prefer a Richmond fringe player as opposed to 28.
Geelong effectively trade Motlop for Henderson. Motlop has offers at 750k. No one will get him for 550k. He is leaving for money, nothing else. Henderson just wants out of Carlton and has been offered about 500k by Geelong. I can't see how Motlop on 750k is worth Henderson at 500k in their opinion plus a pick downgrade. That is saying Motlop is worth less than Henderson. Geelong pass IMO.
Richmond do very well. I think if they could get Motlop for 14 and 32 they would be happy. Let alone throwing in Yarran who is worth a late first rounder for free. I think it would be more like Motlop for 14 and 32 and a seperate trade of Richmond's 2016 for Yarran (which will probably be a late first rounder in a stronger draft). Geelong can trade will Carlton separately which will likely involve a late first rounder.
So in a three way (so it is comparable) something like:
Richmond
Out: 14, 32 (or fringe player), 2016 first
In: Motlop, Yarran
Carlton
Out: Henderson, Yarran
In: 14, 2016 First (Richmond)
Geelong
Out: Motlop
In: Henderson, 32 (or fringe player)
