Stacked or Straight-Lined refers to a situation where an official’s view of a play is obstructed, typically by one or more players positioned directly between the official and the action.

In the above scenario, all three officials are straight-lined by players blocking their vision. This limits their visibility on the play and therefore also decreases play-calling accuracy.

When an official is stacked:

• They cannot clearly see the space between players
• They lose the ability to judge contact accurately
• Their angle is compromised

This is one of the most dangerous positions for an official to be in when making a call.

Why this concept matters:

When you are stacked, you are no longer officiating plays; you are guessing when you blow your whistle with a stacked view. Guessing leads to:

• Incorrect calls
• Loss of credibility
• Frustration from players and coaches

Officiating focus:

• Constantly work to adjust your position to obtain an open angle
• Move laterally or change depth to see between players
• Anticipate where plays are developing to avoid getting stacked

If your view remains obstructed:

• Do not blow the whistle
• Trust your partners who may have a better angle
  • If the play is obvious, your partners should reach and help you

Great officials are not just in the right position, but they also work for the best angle.
