Pre snap once previous play is completed and colors have separated
1. Down and distance, signal down box to move and what down to make it.
2. I typically don't look at the box to verify that he can handle this task, our L double checks and signals if there is a discrepancy
3. Tell myself down and distance and where we have to go for a 1st down.
4. Check the clock status if I killed the clock for a first down, or OOB, signal R and U as to what my clock status is if close play OOB.
5. Watch for O' subs without a huddle, if on my side then cross, if from L side, watch defense, if no move is made, continue on, if subs (rarely) then cross.
6. Align receivers that come to my side, I don't step off the line, I move them with signals or verbally.
7. Verify that I don't have a TE or another otherwise legal receiver covered.
8. Count 4 in the backfield.
9. Verify that everyone has been set at some point for 1 sec.
10. I key to the guard for false start, although my focus is primarily on the TE and T, only so that I can see what the DT is doing as far as the NZ is concerned, I have found that if I just key to the T, I tend to lose focus on what the DT is doing.
11. I watch the wideouts primarily out of the corners of my eyes looking for quick jerky movement.
There can also be potential blind spots with all of the doubles, trips, and even quad sets that are out there now a days... at just the right angle slots can "hide" behind the player that splits out wide near the LOS official, I got caught once this year where the slot man moved before the snap (verified by film) and with trips to your side and he is the inside guy completely obscured by the end, you are watching DT, DE, T, wide out, corner in press coverage, there are a lot of things to draw your attention. We discussed it and R looking through should have seen that FST as well, hopefully.
You think, how can they miss those easy calls, that is until it happens to you and you have no idea that you had movement until you watch it on film..
