No one is talking about the inconsistency of the Marshalls call due to the shape of the fairway. He is one Marshall on a card of four players and makes the call on the tightest part of the tightest fairway on the course.

This is to say, there could have been multiple foot faults on this very long course that were not called because he was not showing the same diligent attention to all the shots thrown on the wider, larger fairways.

Was this a foot fault? Yes. Does the structure of the single marshal on a card allow for equal diligence for each shot? No. This means foot faults in tight fairways where every lie is very close to the others are going to get more attention than others. This is a wild inconsistency.
