Kickoff

Every crew will be using the new mechanic this season which you might not have used yet
LJ on the R restraining line
HL on the R 30-yard line
Counting is still the same
What if there is penalty?
How does this affect our movement after the ball is kicked?
Always be ready for the onside kick
Never miss a block below the waist

Pre-snap

Make sure you are following a pre-snap routine
Give your upfield foot to help receivers with alignment
- I use it to help judge shifts
Read the formation and try to make it legal
Need to always know what the current line to gain is
- I yell it to the chains when I am setting them

Scrimmage Play

Know what your vision pattern is on a wide play to your side
Your vision pattern on wide plays to the other side is different
We need to determine accurate progress spots
Use cross-field mechanics to get the correct spot whenever needed
Help your umpire out by mirroring spots and holding until released
Know your vision pattern on pass plays
On every pass judge if it is forward or backward, beyond or behind
Be ready to rule receivers inbounds or out of bounds, communicate with BJ when needed

Coach Communication

The communication that line of scrimmage officials have with coaches can make or break a game
Always make sure you have a chance to introduce yourself before the game
Be approachable to coaches, sometimes they are just venting, but answer any questions that are asked
Try to give them information before they even ask for it

Crew Communication

Make sure you understand how the crew will use radios
Line of scrimmage signals are optional
Always confirm with another official if you have flags on the same action
Make sure you know how your referee want penalties reported, and do it, don’t be in a rush
Confirm that penalties is enforced correctly

Situational Awareness

Sense the demeanor of the teams and any rising tension amongst players
Aware of timeout situation
Be ready in hurry up offense
Handle a blowout game, letting it end
