Thanks for answering!
How does this sound?
22, 24, 26 and 44 from 2015, 'Pies 1st round 2016
for
27 from 2015, Treloar, Tomlinson
Gives GWS the points it needs (would have 8,22,24,26,44,45 or over 4500 pts) for Academy players this year as well as an extra first round next year. Then GWS could trade anyone else (Hampton etc) for more 2016 picks ("the strong draft").
Think something like this could work well for both teams. GWS get all the academy guys they are after and will be pick-rich for 2016. 'Pies can keep pick 7 from this year and gain the 2 ATs. Anyway, hope this sounds ok - looks like a win-win to me (or as close as you can get when a star wants to leave - see Beams last year)
