You are missing the point.
Yes, we need the Bucs and Pack to lose one more game and we win out. However, if the Pack lose two, and we finish tied with the Bucs we lose out. So if we finish 13-4 and the Bucs finish 13-4, we need a THIRD TEAM to finish 13-4. With the Cards losing today, if we get to 13-4, that means the Cards then have a minimum of 5 losses. They can't be that third team we need tied at 13-4. So that leaves one team that can help us - the Packers. If the Packers also finish 13-4, that helps us. But if the Packers happen to lose twice and finish 12-5, then that screws us as the Bucs have the head to head over us.
You guys really need to look at the standings and tiebreakers. The Cards losing today does not help us unless you expect, at the very minimum, the Bucs to lose two more games. Look at their schedule. They aren't.
