We are less than 24 hours away from the start of National Signing Day, so let’s take a quick look at how the ACC classes stack up against each other:

1. Florida State (No. 4 nationally)

2. Clemson (No. 8 nationally)

3. Miami (No. 14 nationally)

4. Duke (No. 27 nationally)

5. North Carolina (No. 30 nationally)

6. Louisville (No. 34 nationally)

7. Virginia Tech (No. 37 nationally)

8. Pitt

9. Wake Forest

10. Virginia

11. NC State

12. Georgia Tech

13. Boston College

14. Syracuse

Now, for some historical perspective. I averaged out the class rank for the 11 ACC teams that have been in the league since 2006 thanks to compilations from ESPN Stats and Information. Some might surprise you.

1. Florida State

2. Miami

3. Clemson

4. North Carolina

5. Virginia Tech

6. Georgia Tech

7. Virginia

8. NC State

9. Duke

10. Boston College

11. Wake Forest

The biggest takeaways?

• You can see exactly why Florida State and Clemson have opened up a gaping lead on the rest of the Atlantic. The Seminoles are on pace to have the No. 1 class in the ACC in all seven seasons under Jimbo Fisher. Clemson has turned it on under Dabo Swinney, too. The Tigers have five top-13 classes in the past five years after having only two in the previous five classes. Now, look at the next-highest Atlantic team. That would be NC State, behind five teams from the Coastal. Louisville has had an average class rank of No. 7 in its three years in the ACC so it's not as if they are a Top 25 recruiting program, either.

• Speaking of the former Big East teams now in the ACC, Louisville is clearly leading the pack there, but that's not a huge shock given the program's recent success relative to Pitt and Syracuse. The Panthers' class has averaged a No. 9 rank, while the Orange have averaged a 13.5 (two No. 14s and a No. 13).

• Miami fans already know this, but the recruiting rankings confirm once again how much the Hurricanes have underachieved in the ACC. Miami's average class rank was 2.6; Clemson's was 2.7. Since 2006, Miami has finished outside the ACC top 3 just twice -- both under Al Golden. The first time was in his first year; the second time was in 2013 amid an NCAA investigation. Miami had three straight No. 1 classes in the ACC under Randy Shannon. That's three more than Clemson has had in this time frame. Given all the talent that has come through South Florida, and its class average compared to the rest of the Coastal, the Canes should have played in an ACC Championship Game by now.

• North Carolina has been an underachiever, too, though 2015 finally changed that. The Tar Heels' average class rank was 4.8, thanks to six classes that ranked among the top 4 in the ACC during this time span.

• Duke is on pace to have the best recruiting class in school history. Its previous best ranking? No. 8 in 2011. The following year, Duke made a bowl game for the first time since 1995. The Blue Devils haven't missed a bowl game since.

• 2011 was a dismal year for Virginia Tech. The Hokies ranked No. 10 among 12 ACC classes, its lowest rank in this 11-year period. Is it a coincidence they never won the Coastal after that? Maybe. We'll have a look at that specific class later in the week.

• Two first-year coaches ended up with the ACC's No. 1 class: Randy Shannon in 2007 and Jimbo Fisher in 2010. Both also ranked in the top 10 nationally.
