From Bing/chatgpt 4.0:

If the Seahawks win, it could potentially make it more difficult for the Cowboys if both teams end up competing for a wildcard spot in the playoffs. On the other hand, if the 49ers win, it could help solidify their lead in the NFC West, potentially making the Seahawks less of a threat to the Cowboys’ playoff chances.

So, as a Cowboys fan, you might want to root for the 49ers in this game.
