Almost put this in the Theo thread in Baseball discussions but let's do it here:
With Almora's debut, this means that in this decade(2010-2015):
Theo has had 9 of 13 1st rounders make the majors, and 2-3 of those that haven't still have a fair shot of getting there(Happ, Johnson, maybe Blackburn)
McLeod has had 6 of 10 1st rounders make the majors in that span, with the same 2-3 having a chance, and an 11th pick that wasn't signed.
For a point of comparison, in the same span Neal Huntington is 2 for 9, with 5 having a chance to join them(mostly HS draftees in A ball) plus Appel going unsigned, and Mozeliak is 4 for 15, with ~7 having a chance to also make it.
If you look at it by impact the math is pretty good too:
Theo: 15.2 bWAR, 1.16 per pick
McLeod: 14.6, 1.46 per signed pick
Huntington: 9.2(all Cole), 1.02 per signed pick
Mozeliak: 12.0, 0.8 per pick
