Easy to overlook in all else that happened in the Seahawks’ 22-16 win over Arizona on Thursday night was the result made official what had seemed obvious for a while: The NFC West is now a two-team race between Seattle and Los Angeles.

Arizona fell to 4-5 with the loss and at least two games behind the Rams and Seahawks, who have simply looked like better teams all season than the Cardinals, whose four wins have come against teams that entered the weekend 5-30.

The Thursday night win also means Seattle can sit back Sunday and see if somehow the Deshaun Watson-less Houston Texans can beat the Rams in Los Angeles. The oddsmakers don’t think so as the Rams are as much as a 12-point favorite, the largest spread in any game this weekend.

If the Rams do the expected and beat the Texans, they will improve to 7-2 and stay a game ahead of Seattle. That would leave the Seahawks (6-3) four games to keep pace with Los Angeles before getting their chance to beat them again on Dec. 17.

A second win over the Rams would give Seattle the division tiebreaker. Or, to make the obvious even more obvious, a Rams-Seahawks tie for first at the end of the season would give the NFC West title to Seattle.

And the difference in that is enormous.

Winning the division would mean at least one home playoff game and maybe a first-round bye, given the unpredictable nature of the entire NFC.
