It only takes one.
That is the way the NFL works most of the time, especially when it comes to lines every week.
The Arizona Cardinals opened as -6.5 favorites in their final game of the season, one with a lot of meaning to it.
So, the Cardinals not only get a Seahawks team who would like nothing more to end the season, their worst in the Pete Carroll and Russell Wilson era, with a win, they also have something big to play for.
The Arizona Cardinals could be looking at an NFC West title with a win and Rams loss.
We shall see how the line changes this week, especially with the Cardinals playing at home.
