==== Offensive linemen ====
The primary roles of the offensive linemen (or ''down linemen'') are to protect the quarterback so that he can pass, and to help block on running plays. Offensive linemen generally do not run with the ball (unless they recover it on a fumble) or receive a handoff or lateral pass, but there is no rule against it.

Offensive linemen include the following positions:
: '''[[Center (gridiron football)|Centre]]:''' Snaps the ball to the quarterback to initiate play. The most important pass blocker on pass plays. Calls offensive line plays.
: '''[[Guard (gridiron football)|Left/right guards]]:''' Stand to the left and right of the centre. Helps protect the quarterback. Usually very good run blockers, opening holes up the middle for runners.
: '''[[Tackle (gridiron football position)|Left/right tackles]]:''' Stand on the ends of the offensive line. These are the biggest players on the line, usually well over {{convert|300|lb}}. Usually very good pass blockers.
