And so only about 8% of draft picks are players that really make much of a difference beyond replacement value, and only about 30% see much playing time or make a significant contribution to the team.
That means among the 260 or so drafted players each year, only about 2-3 will have Hall of Fame caliber careers, and only about 21 will be undisputedly good picks- and very good but not HoF caliber players.
Overall, only about two dozen players every draft will go on to have significant careers performing at a high level. That’s not a lot – less than one genuinely good player per team each year.
