In NC we're taught to determine whether the most eligible receiver on our line is on or off, regardless of if it's an TE or not. It helps the wings cover each other as far as illegal formations go.

The Umpire has primary on forward passes past the LOS, with the secondary being the wing on either side, depending on what side of the field it happens on.

The LJ + BJ were supposed to count the defense. Should have been a fist made by both to signal to each other.

There's some other things as well, such as we made a couple of adjustments on the kickoff coverage. For ex. the BJ is supposed to work center-out after the kickoff.
