I left a comment saying that it needed to be updated, then later somebody else commented the same thing, and Quizmaster responded and updated this quiz, and I responded that I had already posted that on this quiz and the NFL team passing leaders quiz, and now those comments are gone but the team passing leaders quiz still says Brees is active.
