Every team in the NBA has a list of misses in the NBA Draft and that definitely includes the Detroit Pistons.
Failing to hit in the NBA Draft is the primary reason the Pistons have been bad for so long, something Troy Weaver has hopefully remedied with recent picks Cade Cunningham, Jaden Ivey and Jalen Duren.
The ability to consistently find impact talent in the draft is one of the things that separates the good teams from the bad, ask the Miami Heat and Denver Nuggets, who routinely find good (even MVP) players in the draft even though they rarely have top picks.
