Chris Barrett and Fili Moala, two friends from high school, are battling each other for this starting spot.

The position is called the “3-technique” because the tackle lines up in the gap between the offensive guard and tackle — known as the 3-gap.

The “3-technique” tackle needs good feet, must maintain leverage from outside in, can’t let anything get outside him and must stay alive in the play.

This position is critical to disrupting an offense and freeing up the nose tackle, defensive ends and linebackers.
