Most guys who participate in minor league baseball amount to zilch, but you have to separate the minor leaguers from the prospects. The Cubs did a piss poor job of developing talented minor leaguers for a very long time, especially positions players, which I can see souring somebody on the notion of following them. However, those prospects are still the lifeblood of every organization and you absolutely do need them. The number 1 reason the Cubs have never enjoyed any sustained success at the major league level is a lack of developing prospects. But that's not because those guys are crapshoots, it's because the management has had its head up its butt. And while the rest of the baseball world learned more and more about the value of prospects, the Cubs stayed stuck in the past.
