Line Judge had an unobstructed view of it from about 10-20 feet away. Not sure whether it was his call to make or not but there was nothing out there to block multiple officials' view of the play. If I was a coach and I was told by an official that they didn't see a violation on a play like that I'd be pretty frustrated. But referees screw up from time to time just like players and coaches do. In general I think MVFC referees are better than some of the clown crews we see in the playoffs.
