I can tell some people here haven’t actually played football.
The official chain is on one side of the field, on the other side is a guy holding a marker and the chevron marker. He’s meant to look across the field and line it up to the official one. You can clearly see this isn’t the side with the official chain because look back 10 yards and there’s no other marker.
Clearly the official who’s meant to eye it up didn’t get it right but that doesn’t matter, it’s not the official one. It’s only there so if someone runs to that side they have a rough idea where they need to get to.
Sorry, no cheating to see here.
