Thanks for putting all of this together! Inman and Buckwalter were complete masterminds. They were the Spurs before the Spurs and deserve much more credit nationally. I mean, in 86 Sabonis AND Petrovic were acquired in the same draft. They were way ahead of their time! It's a shame the early 90's Blazers were never able to win the championship, because those teams were almost entirely home grown, which is so rare in today's game. Even when a poor pick was made (Walter Berry, Sam Bowie), they didn't hesitate to move on, acquiring Kevin Duckworth and Buck Williams respectively.
Sidney Wicks is in the data set I calculated. I find it interesting that although he was ROY, and amassed some solid individual stats (16.8 ppg, 8.7 rpg), he didn't generate much Win-Share. He ended his career with 42.4 WS. For a #2 pick, that's actually a bit below expectation (45.4 WS). BTW - Sidney Wicks' rookie year he averaged 24.5 ppg. His average went down every year for 10 years. I can't recall another player that achieved that (disappointing) feat.
You might want to try using the median of each draft location. This will be less suspectable to outliers.
