again--Gold is generic, there are subtle differences
in some teams verbiage, if the Nose is a 1 is is one thing
if he is in a 2i it could be Bronze, etc... would have to see playbook
anyway, it's 3x1 and it's Gold according to my understanding

it's used for stunting ...

you can see JJJIII as the money and Nick Scott at left safety replacing
him, and presnap Scott tips coverage he's already rotating to the middle
of the field ... probably Cover 3, the right safety fills rotate to medium middle
