Discussed which position designator codes are affected by a 2TE set or Full House backfield.  Explained line changes associated with these personnel packages for the run and pass. Note: I did not mention that on a called pass play (except a screen pass) that you do not do a line change when the play result is a 13 or 21 through 36 on the QB’s card.  Don’t include 13 in counting lines (if your card number is 11, drop to 14). If your line change would take you through 21, use 21 for the result.
