From NSD thru mid April is a quiet period. No contact. Meanung, Auburn will be under investigation for causing Saban to sit with Barry and his boy.
When a recruit is on an unofficial or official visit to a school, the coaches can have as much contact as they like, regardless of whether it is a dead period, quiet period, etc. Those periods apply to off campus contact only.
As far as the kid being shown on TV, unless he was specifically announced, or he was sitting in a section designated for recruits only, I doubt we hear anything from it. Where AU got in trouble a few years back, is the recruit was shown on the jumbotron on the sideline in a designated recruit area.
