Wins and losses for a QB are similar to a pitcher in baseball. On an individual game basis they may not be particularly accurate but when they are aggregated over a career they absolutely help tell a story and are reflective of how good someone is. They are not as clean as in individual sports like tennis or golf but in the context of team sports they are huge. Bill Russell is known as they greatest winner in team sports for a reason. He did not do it all himself. Jordan is the GOAT because he won so many titles. No one ever said that a QB solely wins or loses a game on his own or that Wins and Losses are the only stat that matters but over time they are the reason games are played and should carry every bit as much weight as other counting stats do. It's not an accident that Brady has such a good record in both the regular and post season. The fact that Eli is 117-117 for his career is absolutely reflective of his mediocre ability and the only reason he will even be considered for the HOF is his 2 Super WINS.
