If Kelly decides to leave, and St Kilda would offer the Hawthorn 2017 1st round + Saints 2017 1st round + Saints 2018 1st round, what kind of player or pick might be deemed equitable to be packaged alongside Kelly? It looks like a top 5 + top 12 + top ~14, for Kelly + ????? (based on expected ladder positions).
You're looking at Kelly and a 16-30 player OR a young high draft pick that can't get a game from the Giant's list for that deal (assuming pick 5 is yours). Throw whatever names you want around.
FWIW Hawthorn will give you a pick between 5-9. They're not totally toothless yet.
A lot of water to pass under the bridge before you have your final chips to play with.
