2004 to 2013 drafts, sorting by winshares within that draft. Completely arbitrary numbers I assigned below, but I feel like it gives some sort of idea what type player you might get (obviously not all are created equal with injuries and whatnot, Derrick Rose winds up in the 3rd group for example). Most recent data is also obviously very rough and there's lots of room for movement.
Pick number. Tops in draft in win shares / Top 5 of draft / Top 15 of draft / Outside of top 15
1st pick. 2/4/2/2
2nd pick. 2/0/5/4
3rd pick. 1/3/3/3
4th pick. 1/3/3/3
5th pick. 1/1/5/2
6th pick. 0/1/2/7
7th pick. 1/3/1/5
8th pick. 0/1/5/4
9th pick. 0/3/5/2
10th pick. 0/1/4/5
Just for fun all the guys in the top 5 of their draft years who weren't top 10 picks.
2004- Al Jefferson, Kevin Martin
2005- David Lee, Danny Granger
2006- Paul Milsap, Kyle Lowry, Rajon Rondo
2007- Marc Gasol
2008- Serge Ibaka, DeAndre Jordan, George Hill
2009- Ty Lawson, Taj Gibson
2010- none
2011- Kawhi Leonard, Jimmy Butler, Chandler Parsons, Kenneth Faried
2012- Draymond Green
2013- Mason Plumlee, Gorgui Deng, Rudy Gobert, Giannis Antetokounmpo
Top 4 picks in most drafts seem to be generally more successful, and being 6th pick seems like bad luck.
