Just went back through the last drafts and picks that turned into players that are either best 22 or should really be best 22 soon. Left out Hutch for personal choice but his inclusion wouldn't change the analysis much.
2007: Masten
2008: Naitanui, Shuey
2009: Sheppard
2010: Gaff, Darling, Lycett
2011: -
2012: -
2013: Sheed, Barrass (jury out on Karps)
2014: Duggan, Nelson (Waterman/Cavka very outside chances, Lamb will be gone in 12 months IMO)
Yeah fair enough, perhaps the number is somewhere between 1-2. But as I said, considering the fact that we have traded out of the draft, and it is particularly weak this year, a 50 gamer in the late 30s is not a bad result IMO. Provided our first pick does play a decent amount of games for us too. That would be say, 1.5 best 22 players from the draft. About right.
You have to also look at the way we've traded in a third of our best 22 to plug the gaps in our drafting:
Kennedy
Yeo
Hill
Cripps
Redden
Jetta
Ellis
Nice work. Adding to your analysis -
2006 - Priddis (rookie draft), Brown, EMac, Schofield
2007 - we also did get Ebert and Selwood who were B22 most of the time
2009 - wtf happened here (other than Shep)? No wonder we finished bottom in 2010.
2010 - wooden spoon was very helpful but not ideal timing as we had all the GCS concession picks taking many of the best players.
2011 - Gov (rookie draft). Another awful national draft with all the GWS concessions.
2012 - We did get Sinclair from the following rookie draft at least.
As for trading...
JK (+ pick #3 used for Masten + #20 for Notte) was for Judd (B22?

+ pick#46 (Carlton took Dennis Armfield)
Hill for Pick #49 (Bulldogs took Daniel Pearce)
Wellingham for Pick #18 (Collingwood took Brodie Grundy)
Cripps+#45 (Colledge) for Picks #40 & #43 (St Kilda took Brodie Murdoch & Josh Saunders)
Redden for Pick #17 (Brisbane traded it for academy points)
Jetta for Sinclair (straight swap with Sydney)
Looking at all this I think the recruiters at West Coast have done an amazing job over recent years. Trading in 10 (6 of which are currently B22) players since 2007, and then managing to identify talent to build the list up from the drafts when our picks haven't been that fantastic is really impressive. Kind of helps when you manage to get a Brownlow medallist, a backup ruckman you later trade for a quality mid, and one of our best up-and-coming superstars all from rookie drafts mind you.
I don't think the upcoming draft is as bad as most are suggesting. We are approaching it with a lean (38-6) profile so we'll only have 3 live picks. And if you look through our current list the correlation between early draft picks and our best players is far from a linear one. I think there are some potentially quality players at our first two picks and our third could still land us a solid keeper. We just have to pick the right ones for us and invest in them like we have with our current list (I truly hope Simmo stays with us for a long time). Hopefully we'll also add another superstar to our rookie draft trophy cabinet.
