Many of today’s quarterback rankings or supremacy debates are rooted in the subject of quarterback wins. That is, rather than exalting individuals statistics like passing yards, passing touchdowns, DVOA, or Pro Football Focus grades — you know, the items an individual quarterback can control — wins and losses are assigned to his name. Just as a tennis fan would prop up a tennis player’s win-loss numbers, quarterbacks get lassoed in that, too.
Never mind the notion that a head coach exists on every NFL team to be held accountable for winning percentage — pundits and fans enjoy holding one person (the quarterback) of 53 players as the keyholder for victories.
