Defensive calls Illegal...?

[InsideTheStripe]

Below is the referenced case play RadioBlue.


9.5.1 SITUATION B: B1 calls defensive signals loudly: (a) before A takes its set position; or (b) during the time A1 is giving his cadence count; or (c) while A1 is using audibles. RULING: Legal in (a). In (b) and (c), if in the official’s judgment the action by B1 was for the purpose of disconcerting or hindering A, it is an unsportsmanlike-conduct foul. In this case, the official should sound his whistle before the snap. (9-5-1d)




While looking for that case play I came across this...

7.1.7 SITUATION C: On third and 10 from A's 40-yard line, all team A players are set. While quarterback A1 is calling signals, defensive back B1, starting from a position eight yards behind his line of scrimmage, runs toward the neutral zone. B1 stops directly in front of tackle A4 but does not enter the neutral zone. In response to B1's charge, A4 (a) does not move, or (b) flinches. RULING: No foul in (a). In (b), A4 is guilty of a dead-ball foul for false start. If in the official's judgment the action by B1 was for the purpose of disconcerting or hindering A, it is an unsportsmanlike conduct foul. In this case, the official should sound the whistle before the snap. (7-1-7; 9-5-1d)

Anyone ever call USC on a defensive player that rushed the line and didn't enter the neutral zone?
