Definition & Meaning of "interior offensive line"in English

What is the "interior offensive line"?

The interior offensive line in American football consists of three central positions: the left guard, center, and right guard. These players are responsible for protecting the quarterback and opening up space for the running back to advance the ball. The center is positioned in the middle and snaps the ball to start each play. The guards are placed on either side of the center and help block defenders, preventing them from reaching the quarterback or disrupting running plays. Together, these players form the core of the offensive line and play a key role in the team's success.
