A few notes regarding the 4-0 record NFC West teams combined to produce in Week 2:
This 4-0 mark for one week was the NFC West's first since Week 10 last season. It was the second since divisional realignment in 2002.
2012 NFL Records Outside Division
Divisions have relatively few opportunities to go 4-0 in one week. The presence of even one division game or bye week on the schedule rules out the possibility.
The NFC West had five weeks featuring four non-division games last season. The division went 0-4 in Week 2, 1-3 in Week 4, 2-2 in Week 8, 4-0 in Week 10 and 3-1 in Week 15. Those records suggest improvement for the division. Put it this way: The NFC West has gone 11-1 in its last three shots at going 4-0.
None of the NFC West teams played a perfect or near-perfect game Sunday. Seattle might have come closest during its 27-7 victory over Dallas. Arizona's offense suffered multiple turnovers. Larry Fitzgerald finished with one catch. San Francisco endured multiple dropped passes and its first turnover in 26 regular-season quarters. St. Louis gave up a fumble return for a touchdown on its first offensive play. Later, Sam Bradford threw an interception in the end zone.
Every NFC West opponent in Week 2 won its opener. Three of the four -- Dallas, Washington and New England -- won on the road in Week 1. The Lions were a playoff team last season. It's not like the West loaded up on cupcakes.
Every NFC West team has held a fourth-quarter lead in each of its two games this season.
NFC West teams play four non-division games in Week 3: St. Louis at Chicago, Arizona vs. Philadelphia, San Francisco at Minnesota and Seattle vs. Green Bay
