At 4 eastern the NFC West Power system play is on Arizona. The Cards are in 2 power systems here today and one that dates to 1989 plays on Division road teams on grass that are not getting mote than 8 points and are taking on a team off a home favored win if they had less than 200 yards passing and are off a loss in their last game. The Cards also fit a game 5 system that pertains to 1-3 and teams off a loss vs a team off a win. Arizona is better stat wise than their record and should play the Niners tight. SF was able to ease past the Pats last week in a game where they had a pick six which made the score look worse than it was. Take the points here
