2016 Recruiting Class - Best Defensive Class Since???

Was just thinking about how good everyone on the defense is playing this year, and was just realizing how many of them were a part of the 2016 Class. These are the defensive contributors from the 2016 class(composite rank in parentheses):

1. Rashan Gary (1)

2. David Long (65)

3. Lavert Hill (132)

4. Carlo Kemp(310)

5. Devin Bush(312)

6. Khaleke Hudson(386)

7. Josh Uche(707)

8. Josh Metellus(739)

9. Michael Dwumfour(947)

10. Devin Gil(997)

Thats 10 Players. 9 of which have started games this year, and the 1 that hasnt started is leading the team in sacks(Uche). 4 are All American Quality(Gary wont be because he missed games), I bet 2 or 3 more make All Big-10 lists. 

I mean when is the last time we have had that many good players/contributors from 1 class on 1 side of the ball? Just having 10 players from 1 class as rotation players on a defense is alot, but the fact that they are all major contributors of the #1 Defense in the country. Thats pretty nuts.

Can anybody think of a single class from the past that had that big of an impact on 1 side of the ball before? I am just talking Michigan history, because I am sure Alabama has had some crazy 6 5-Star Class that was all on D probably.
