There are only 32 1st round picks. From 15 ACC teams you had 9 picks. That means they had 9 of the best players on the country. Unless you have 3-4 on 1 team it will have little impact on the individual team's performance. FSU was a top team so them having a top kid is expected.
The NFL draft is based a lot on talent and potential and not always college stats. Yes you had 2 QBs with great statistical careers but when you have linebackers and defensive line players they look at their size, speed, quickness, and what they can offer at the next level. For O-line they look at size and how they did but a great lineman on a bad team vs a decent lineman on a good team is tough to evaluate. We had Anthony Davis who was a 1st round pick but our teams were not tremendous in the years he played but just good.
