Well aware of this. But that was a decision the Mets made to go over slot to get a guy that had fallen to them. It was a common strategy they used under that regime. It's still a bit of a blow to fall from 30 to 53, which is what he did. The Mets just wanted to make sure they got him signed (and at the end of the day, he didn't fall THAT far).
The Dodgers were also not ever going to have the slot money needed to sign him in 2018 at that pick number. They rolled the dice to see if he would turn down about $1.8 - 2 million, and he did. Dodgers overdrafted him and the Mets underdrafted and overpaid. His stock the whole time was that of an early 2nd rounder, and didn’t really move at all.
