For those who are interested in deeper details:
As far as the Cardinals are concerned, a loss by PHI or NO carries more weight than a loss by SF or MIN. That is because SF and MIN still have to play the Rams. If the Eagles or Saints lose a game, to keep us out of the playoffs, it forces BOTH the Vikings and 49ers to win out (49ers can tie one), handing the Rams two more losses. Then, to knock us out, the Rams would HAVE TO either beat the Ravens, or have their game against SF finish exactly in a tie.
There is also a very unlikely scenario where PHI/MIN/ARI finish 10-7 for the last two spots, and we sneak in, but would require the Eagles to overcome a massive strength of victory deficit against MIN.
