General Philosophy

The three-official system provides effective coverage for all plays through the proper positioning and movement of each official. Each official has specific zones of responsibility and works together as a team to ensure every play is properly covered. The key to success is maintaining proper spacing, angles, and following the prescribed keys for each type of play.

Kickoffs & Free Kicks

Referee (R)

  • • Positions 10-12 yards deep, wide of kicker
  • • Keys: Kicking team (deeps) & return team (Gunnars)
  • • Primary: Long returns, blocks, catches

Umpire (U)

  • • Positions at kickoff yard line
  • • Keys: Kicking team (inside)
  • • Primary: Blocking, goal line coverage

Linesman (L)

  • • Positions on line of scrimmage
  • • Keys: Return team (wide)
  • • Primary: Offside, illegal formation

Running Play Procedures

R

Referee

Follows the ball from behind, keys on the lead blocker or ball carrier. Works toward the LOS on every play. Observes the action around the ball carrier, especially during tackles and piles.

U

Umpire

Faces the LOS, keys on the first down lineman. Observes the line of scrimmage for holding, illegal blocks, and false starts. Monitors the QB on play action.

L

Linesman

Faces the LOS, keys on the widest receiver. Watches for motion, illegal formation, and pass interference. Counts players, observes the sideline for out-of-bounds plays.

Forward Pass Play Mechanics

Pass Progression & Keys

Referee Keys: QB → #1 receiver → Deep

  • U 7-10 yards deep, opposite punt
  • L On LOS, wide side

Post-Snap Movement

  • R: Follows punter, keys returner
  • U: Monitors blocking, goal line
  • L: Counts players, watches sideline

Field Goal, Try & Goal Line

Field Goal/Try Positioning
