This. Telling your front or back player on your side of the field what you see is key. If you are playing back on snake player, let him know "S1 is posted waiting for you", "D2 is looking inside" , "stay low, home is putting a lane on you", "You're clear, bump". If you're a snake player, let your back know what you see also or ask him what he sees. If you're at the 50 I'd advise to just listen as your home player should be giving you information and not talking, as someone could be on the other side of the 50.
