This time it isn't just one safety being occupied, but both. Joyner is locked on Cobb in one slot, and Johnson is locked on Graham in the other. Before the snap, Rodgers gives Adams a hand signal, presumably changing his route to the deep post as the QB suspects the slot route combination will keep the safeties shallow. Johnson even turns his body when Graham makes an out cut, taking himself out of any potential deep help. When Rodgers reads both safeties staying roughly square to the line of scrimmage and not helping deep, it's bombs away.
