No offense, but you've spent the last 2 votes on a 19 year old with 50 career at bats in the United States, who likely doesn't start next year above the AZL, and who I would guess you've seen no video of and read next to zero scouting reports on.
You have essentially no ground to stand on when it comes to critiquing someone else's selection this high in the rankings.
Acosta likely doesn't make the top 20.
Edited to add: It appears that the highest any player who hasn't cracked the AZL has ever started is #28, which was Fidel Castro last season. This doesn't count FAs who were given deals in excess of a million dollars (Chapman, Iglesias, Garcia, AlfRod) who are clear exceptions.
