Mark is right there is no secondary defender in the NF rules. But also we overuse that term IMO as I can see a secondary defender as an outside official if the play is in the lane. In some cases, the secondary defender is more clearly seen by the C or T as they saw where they came from, unobstructed.

I totally disagree that someone other than the L cannot call a foul on a secondary defender when they see the play the entire way. The secondary defender is only involved in the NCAA (Men's) if the defender is in the Restricted Area. Outside of that, the secondary defender is not a factor in a call in the lane other than if there is a double whistle who gets the call. I have talked with many that modify that based on the play or situation.
