The median drop-off kind of is what it is. I'm assuming the veracity of the data is fine, which if it is, the drop-off appears to exist. As I said, the 5th overall seems to be a bad luck pick of sorts, looking at the median outcome. And the median outcome was used and not the mean, I assume, because it eliminates the fact that every slot in the first round of the draft has had superstars drafted in it and that skews the average outcome of the pick. If you have 20 nobodys, and also Babe Ruth, it's going to look like the average is pretty decent. There's only a little over 50 years of data, so with that sort of small-ish population, large numbers at the top can still definitely skew an average. Should teams feel that drafting at 14 overall is a lost cause? Of course not. Luck and scouting skill can absolutely increase the odds. But "should" the 14th overall be a solid MLB contributor? History seems to indicate that should not be a foregone conclusion, or even be assumed to be a likely outcome.
