Good bump so I could re-nerd out on this post.Here's my proposed methodology for judging success of picks using Draftguru data.
Compare how many games the Geelong player played with the average of the selection they were taken with in the National Draft. For example, Andrew Mackie played 280 games whereas the average for pick 7 is 109 games so Geelong is +171 for that selection. In contrast, Kane Tenace played only 59 so that's a -50.
That gives you these results:

Obviously, for the picks from recent years they haven't played out their careers yet so the negative numbers don't have much meaning (except say Hayball and House who are gone on 0 games).
If you sum the "Diff" column up to and including 2011 selections you get +1183. That is, over the period 2007-2011 Geelong got 1183 more games out of its draft selections than the average for those same selections taken across the league. Or an average of 118.3 games per draft year over and above the average (or +25 games per selection). That's an enormous batting average and goes a long way to explaining why Geelong had the success it did in 2007-2011.
Since 2011, the story is much more grim. We are at -545 at an average of -90 per draft or -29 per player. Now obviously a lot of that can be attributed to the players that are still playing and so to the extent that they extend their careers those numbers will improve. But of the list only Thurlow, Lang, Kolo, Cockatoo, Cunico, Buzza, Menegola, Parfitt, Stewart, Narkle and Abbott remain. They would have to play 1020 games between them to bat at the same average as the 2002-2011 crop. Given 4 or 5 of those names probably won't play another 30 games between them that seems a big stretch. Currently, only Kolo and Menegola are batting above the games average. Every other selection in that period is behind the average and seven of those are no longer on an AFL list.
If you look year by year you can also see that success for 2002-2011 with Wells only failing to beat the average in one year out of 10 (2003) thanks to busts with Tenace, Thurley and Spencer:

Then you can break it down by round of selection (2002-2011). This ratifies the Wells' reputation for making great selections with 3rd and 4th round selections:
