Let's face it. Fair trades rarely get done because the player nominates a club and the club can only deal on what assets they have.
Pick 6 is overs. I can't recall an uncontracted player being traded for a pick that high since Judd - who was a Brownlow medalist and premiership winning captain. Judd and Carlisle are miles apart.
Pick 25 is clear unders but that's St Kilda's next pick so that naturally becomes part of the trade but obviously with something else such as another pick or a player. That player isn't going to be a contracted gun. It's more than likely going to be an expendable type that Essendon like.
I know most St Kilda fans won't like it but if we keep pick 6 and grab someone like Mathieson (inside mid) then Jobe's cousin (former pick 25 draftee) becomes expendable IMO. The other name that's been thrown up is Tom Hickey who may appeal to Essendon.
Don't expect we'll get upfront value for Carlisle as that's just what happens when a player leaves your club.
However I don't think dud players will be part of the deal because it just never happens. Quality + shit does not = more quality.
It was the same last year. All trade week we heard Ryder for pick 17 + Butcher and Essendon were stupid for not taking it.
In the end Port did what everybody knew they would do and changed it to 17 + 36 and the deal was done. It still wasn't great for Ryder I think but a spud like John Butcher was never going to be involved in such a trade.
In fact I think the deal was the real spur for future pick trading as both clubs said they'd have immediately accepted pick 17 + 2015 Round 1 pick for Ryder.
If Carlisle wants to go to another club they'll work something out in the ballpark of value.
