Place boundaries about 15 yards apart to represent the sidelines of a condensed field. The line of scrimmage for this drill should be the five yard line, so indicate that the goal line is only five yards from the line of scrimmage.
Simulate a condensed portion of a full speed play by pitting three offensive players against three defensive players.
The Oklahoma Drill is a classic contact football drill. It pits three offensive players vs. three defensive players. Each side has two linemen facing off at the line of scrimmage. The defensive has a linebacker behind the line in opposition to the running back behind the offensive line.
At the start of the drill, the lineman clash at the line of scrimmage will the running back makes his move for the end zone. The running back must find and select one of the three gaps amidst his blockers while keeping in mind that he will have to face the linebacker behind the line.
The offensive linemen do their best to block their man, while the defensive lineman will do their best to shed to block and make the tackle. The linebacker will start with his feet on the goal line and mirror the running back while trying to meet him as close to the line of scrimmage as possible since he has no room to give up behind him before the end zone.
This drill does a great job of simulating a condensed portion of a play in a goal line situation.
