Freo have Farmer and Medhurst, doubt they will acquire another one, unless they ship Medhurst to somebody.
West Coast have Sampi (who i reckon is overrated) and Matera, but he is 30 and having injury troubles.
Realistically, i'd be hoping for mid 20's pick for him, you won't get higher due to his contract situation (he has 2 years left of contract, good one Tigers trading ANOTHER player and having to pay his contract!)
Some ideas:
Krakeour for McConnell?
Krakeour for Pick 34 (WC)
Krakeour for Adkins, Pick 50?
Krakeour for Pick 26 (Freo)
