I'm guessing the nametag is from a former fazbear entertainment employee that worked in the same position as william but was killed by an animatronic. Maybe this or I'm suspecting that Steve raglan is another one of William's fake identities like Dave miller this is theory is widely accepted by people who noticed that nametag says Steve raglan. Another theory is that William Afton is just filling in for Steve raglan because he got the day of or he's on his lunch break or something... But that's just a theory, a film theory!
