Hawthorn is based in Melbourne, plays blockbuster games at the MCG, has a history (including a recent history) of success, is the second biggest club in the AFL by members and has the best coach in the league. It's fair to say there are some institutional advantages at Hawthorn's disposal that aren't available to Freo. I'm not dismissing that the best club in the AFL runs its shop better than Freo, but to ignore those institutional advantages is also foolish.
I agree we did poorly in the draft from 2012-2015, but I don't think the Hawks did any better. Freo brought in Pearce, Landon, Weller, Tabs and Blakely as the best 5 players drafted in that time. The Hawks, over the same period, brought in Sicily, O'Brien, Hartung, Burton and Ceglar as their best drafted players in that time. For both clubs it falls away steeply after that. I'm not sure the gulf in talent between the clubs is due to drafting over that period.
