Pulling from the 1990-2010 draft data set that I used for the graph of the week. Here’s how often, by round, that players picked by the Cardinals have made it to MLB.
Interesting spike there in the mid-twenties. Honestly no idea how this relates to league average, I’ll have to go get some more data to do that comparison. That said it’s the pattern you’d expect, a linear-ish decline and then a bunch of random humps and bumps the further you get out.
