also: post blocker · post
The blocker in a combination who prevents the down defender from splitting the double team. Post is a job inside the combo, not another name for the combo.
The post man keeps the down defender from penetrating between the two blockers and gives the drive man a surface to move. Many systems make the covered or inside lineman the post, but that is a rule inside the system rather than the definition of the word. Post does not mean stay on the down defender for the entire play, either. The linebacker's movement and the combination's release rule decide which blocker leaves.
