‘But the Bills aren’t really who they seem to be on paper, a sleepy third seed in the AFC behind Tennessee and Kansas City. Here are categories in which the Bills led the entire NFL: yards allowed per game (272.8), yards allowed per play (4.6), passing yards allowed per game (163.0 — a number that seems as if it’s from the 1960s), points allowed per game (17.0) and third-down conversion rate allowed (30.8 percent). Seems as if their defense might be at least fair to middling.’
