I have an authentic “game worn” #15 blue home jersey worn by Kevin Drake of the Bills. Got it off the Bills website in the early 2000s. Kevin was a 2000 practice squad WR that never saw the field, as best I can tell. But he had a jersey with his name on it! Maybe it is actually “practice worn. He’s a prep school football coach in Alabama now.
It is the traditional royal blue and the only stitching is the Puma emblem. Everything else is painted on.
