it's almost certainly not. it's very, very, very rare for any minor league system to produce that many good players without many busts. let's take a look at the BA top 30 for the cubs in 2001: 1. corey patterson 2. juan cruz 3. hee seop choi 4. ben christensen 5. carlos zambrano 6. luis montanez 7. david kelton 8. bobby hill 9. john webb 10. nate frese 11. eric hinske 12. julio zuleta 13. aaron krawiec 14. wilton chavez 15. ryan gripp 16. michael wuertz 17. joey nation 18. scott chiasson 19. jeff goldbach 20. mike mallory 21. carlos urrutia 22. ryan jorgensen 23. steve smyth 24. ross gload 25. will ohman 26. chris gissell 27. matt bruback 28. jaisen randolph 29. jason smith 30. nic jackson only one real star (zambrano) in that list and then a handful of guys who made some contribution, and a whole lot guys who flamed out well before getting close to the majors. as for teams that did the best job of turning players in the top 30 into major league players who stuck for longer than a year or so, these were the best that year (along with where BA had those players ranked): braves: wilson betemit (1), marcus giles (3), matt belisle (4), jason marquis (5), adam wainwright (7), wes helms (8), horacio ramirez (11), damian moss (19), kelly johnson (25) white sox: jon rauch (1), joe crede (3), matt ginter (4), aaron rowand (8), josh fogg (9), gary majewski (11), rocky biddle (13), matt guerrier (16), miguel olivo (17), josh paul (20), gary glover (22) indians: sabathia (1), danys baez (2), willy taveras (4), jake westbrook (7), brian tallet (14), david riske (15), jhonny peralta (19), ryan church (30) rockies: juan uribe (2), aaron cook (4), jasno jennings (6), shawn chacon (8), matt holliday (10), garrett atkins (17), brad hawpe (18), josh bard (23), jody gerut (30) marlins: josh beckett (1), miguel cabrera (3), adrian gonzalez (4), claudio vargas (6), blaine neal (7), pablo ozuna (9), denny bautista (14), josh wilson (17), jason grilli (20), nate bump (30) twins: michael cuddyer (2), luis rivas (4), justin morneau (5), rob bowen (7), bobby kielty (8), juan rincon (13), grant balfour (15), kyle lohse (16), a.j. pierzynski (18), j.d. durbin (20), chad moeller (23), lew ford (24) expos: brandon phillips (2), brad wilkerson (3), grady sizemore (6), brian schneider (13), cliff lee (21) - really just including them because they turned out three really good players and not much else a's: ryan ludwick (3), freddie bynum (6), chad harville (7), eric byrnes (9), gerald laird (11), luis vizcaino (14), mark ellis (17), jon adkins (19), chad bradford (22), aaron harang (27) phillies: jimmy rollins (1), brett myers (2), ryan madson (4), chase utley (5), brandon duckworth (9), marlon byrd (10), johnny estrada (19), carlos silva (20), jason michaels (24), taylor buchholz (26), nick punto (29) devil rays: josh hamilton (1), carl crawford (3), aubrey huff (4), bobby seay (8), rocco baldelli (9), travis harper (10), toby hall (11), jason tyner (14), jorge cantu (19), seth mcclung (21), alex sanchez (24), joe kennedy (26) blue jays: vernon wells (1), felipe lopez (2), cesar izturis (3), josh phelps (10), mark hendrickson (11), ryan freel (12), jayson werth (14), dewayne wise (15), brandon lyon (16), alex rios (17), chris woodward (19) so it seems like 12 of 30 is about the highest number that these teams had contribute at any level to the major league team. as far as overall positive contributions, seems like the marlins, phillies and maybe twins did the best with the players in their system.
