Pick 5 wouldn't get you within a bulls roar of Cameron or Hogan.only way you would get something near his value is a three way trade.....
Freo trades pick 5 to gws and gets hogan
Demons lose hogan and gains Patton/cameron
GWS loses patton/cameron and gains pick 5
Saying that i wonder what lachie neales worth
Look at the Dayne Beams trade - it took pick 5 + Greenwood + Crisp (essentially) to secure him and Hogan/Cameron would have even more currency than Beams.
Neales worth would have to be pretty close to Treloar - would have cost a club about the same (this year 1st rounder, plus next years 1st rounder and some other picks swapped around)
