The hit rate is marginally better. But then from 2005 to 2014 (randomly chosen 10 year stretch long enough ago to mean something), the only player drafted at 16 to eclipse 4.0 fWAR in his career was Brett Lowrie. (Lucas Giolito and Jeremy Jeffress might one day.)
26 has no one close, in fact the only players in that timeframe drafted at 26 with positive fWAR are Michael Chavis and Blake Swihart (both drafted by Boston).
However, there were a lot of good players on the board every year at 26. If for example, we randomly chose drafting 32, both Jose Berrios and Aaron Judge would be better picks.
I don’t think the Sox are going to consider the draft at all when deciding what to do inJuly. They will consider 2020 and beyond, but not the draft. Not like DD is such a great drafter anyway...
