saw a very interesting exchange between a head coach of a major NCAA football team and the H during a game. I was right there charting fouls for the crew and saw the A player lining up in the slot clearly beyond the LOS. The Head Coach of B was on the line and said to the H "he's on" like he knew he wasn't but it was ok and walked away. To put this into context the game was not very close but still in the first half. I saw another play where a defender was lined up in the neutral zone but that also was a no call. Is there a philosophy on when to call lining up in the neutral zone and does each linesman have his/her own?
