After 18 weeks of football, it's incredible to think there are still unknowns and mysteries surrounding the remaining playoff teams. To a greater extent than any other American sport, football is still subject to simplistic stories of who wanted it more and arguments that don't reflect what actually happened on the field. The last big play of wild-card weekend was a missed field goal that nobody realized was a blocked kick for about three hours. That doesn't happen in other sports.
In other cases, an argument that might have applied to a team in the past hasn't actually been checked to see if it reflects the current squad.
