It would be interesting to evaluate MLB rookies per team over the last 5 or so years by WAR or something. Even though the Astros farm system is ranked usually in the 28 - 30 range, I suspect that the actual value at the MLB level of players coming out of the system is much, much higher.
Ditto. If there’s a tool that can swing a search along the lines of “cumulative WAR per team by each team’s homegrown players aged 26 and under” that would be really cool. I know Baseball America has done somewhat regular articles on this in the past, and as you’d expect, for many years the Astros have outperformed their farm system rank.
