You look at MLB's team rankings (which weights prospect quality)
The ten playoff teams rank:
Cubs (29), Red Sox (28), Yankees (24), Brewers (23), Guardians (19), Rockies (18), Dodgers (11), A's (9), Astros (5), Braves (2)
So 6 teams in the bottom half of prospect rankings, 4 in the top half. So the correlation of this year's prospect rankings aren't that useful.
