From SABR member Derek Bain at Seamheads.com on September 30, 2015:
In “Hardball Retrospective: Evaluating Scouting and Development Outcomes for the Modern-Era Franchises”, I placed every ballplayer in the modern era (from 1901-present) on their original team. Therefore, Ty Cobb is listed on the Tigers roster for the duration of his career while the Mets declare Tom Seaver and the Pirates claim Barry Bonds. I calculated revised standings for every season based entirely on the performance of each team’s “original” players. I discuss every team’s “original” players and seasons at length along with organizational performance with respect to the Amateur Draft (or First-Year Player Draft), amateur free agent signings and other methods of player acquisition. Season standings, WAR and Win Shares totals for the “original” teams are compared against the “actual” team results to assess each franchise’s scouting, development and general management skills.
The General Manager Scorecard results from further research exploring the databases that I utilized while writing “Hardball Retrospective”. My findings include the career Win Shares and Wins Above Replacement totals for all players signed to their first Major League Baseball contract by every General Manager from 1950 through the 2013 season. I will provide outcomes calculated by the plate appearance (PA) and batters facing pitcher (BFP) totals. I have restricted the conclusions to the 1950-2013 timeframe in an effort to correspond with the entries in the Baseball America Executive Database. Furthermore, I have omitted all transactions except for the player’s initial MLB contract; the General Managers are not evaluated on trades, players drafted but not signed, etc.
