The large number is impressive — but just as amazing is how late some of the key contributors were taken by the Cardinals. In the dynamic ultra-young just-formed bullpen alone, Seth Maness was an 11th rounder, Trevor Rosenthal a 21st rounder and Kevin Siegrist a 41st rounder.
The Cardinals are quite the consistent success story, carrying their draft and development success for many years, especially under Luhnow.
Luhnow doesn’t hesitate to say they could duplicate it in Houston as well, where the Astros have posted baseball’s worst record three years running while the team has stockpiled two draft choices.
