The San Francisco 49ers have quietly become favorites in the NFC West. Kyle Shanahan has done an extraordinary job in a season filled with injuries, including Brock Purdy’s, to keep the team as a contender.

After a very inconsistent start to the season with a 6-4 record, the 49ers began to get healthy and now have six consecutive wins. In a historic opportunity, they could clinch the No. 1 seed in the conference as well as the division title with a victory over the Seahawks in Week 18.

That would give them home-field advantage throughout the playoffs and even the Super Bowl, since Santa Clara will be the host city for that game. However, a loss could change the entire path for the 49ers in the postseason.
