I get where you're coming from, but in recent memory
2014: Rodon was the layup projected #1 the year before
2015: Mautuella (I believe went in the 3rd?) was seen as a #1 pick until injuries hit
2016: Groome was rated MLB Pipeline's #1 prospect, Puk was projected as the #1 pick
2017: Twins took the 5th ranked guy to save money
2018: Singer was THE guy for so long, then he wasn't. Then Turang for a bit.
The draft changes a lot man. Adley can fall a spot or two.
