None of the top rated safeties in mainstream went on to play like top safeties and while Fitzpatrick had a couple good seasons following a trade to Steelers he's only got 12int's his career.
Splitting hairs a little, but you could argue Minkah was rated as the 2nd CB in 2018. Although the Dolphins tried to use him more as a positionless hybrid player and he was traded to the Steelers who moved him to his best position.
Derwin was the first true FS drafted that year in my eyes, and he has the All Pro votes to prove an early FS can still be worth the selection.
