Ready to take your defensive line to the next level? In this video, we break down the  Bump and Under shifts to help solidify your edges and give yourself a definite C Gap presence.

The presenter in our video is Brian Nix, Head Coach at Alcoa High School in Tennessee.  The video is a portion of his Tite Front System that can be found on Glazier Drive.

This specific segment is from his video: [Bump, Mint, and Under](https://production.glazierdrive.com/systems/lessons/bump-mint-under).

 

A few of our Takeaways

1. **Bump **is a call that they use frequently in their defense.
2. The defensive linemen move one full gap to the next adjacent gap.
3. They can call bump left or bump right.
4. Purpose is to give their defense a more solid edge.
5. Also gives them a true C Gap presence, and it allows the defensive end to be more decisive.
6. Bump opens the B gap, but changes the fits so that one of the linebackers is now the B gap defender.
7. The linebacker reads do not change in bump from their base Tite Front defense.
8. **Under **is one of the most frequent calls that Coach Nix makes.  
9. The only difference between bump and under is that in "Under" the nickel will walk up to the line of scrimmage.
