Anybody come off your sideline, anybody come on?
ID your widest receiver, is he a back, is he an end? What's his #?
Is your end "covered"?
Who is your tackle? What's his number?
4 in the backfield/7 on the line? Signal your opposite partner.
Watch the LOS. Anybody flinch, anybody jump, snapper twitch the ball?
SNAP
Cover the play.
Spot or mirror spot.
Repeat

Never let a player behind you without knowing where he went and what he did.

This list was something I really wanted. Thanks man!
