Making the Call - Eye Contact Essential
Referee who SEES the violation, whistles

Dual System of Control
Out of bounds responsibility

Keep play in between on the 30-40 yard rope
Adjust to flow – Lead Official keys on Lead Attacker

No Touchline Hugging
Flexible Pattern – requires high work rate to stay close enough to play and still be able to cover the offside decision

Covering “coffin corner”
Trail must press down with play. Lead is usually screened and must split his focus to determine offside.

Running off the field may be required
Just like diagonal system? Lead referee should be closer to the goal than the thrower, in order to cover goal scored as well as offside.

Play near the goal
Lead referee across the goal may be necessary, but may also compromise the offside decision.
