No. 1: 49ers get No. 1 seed and home-field advantage
Let’s get the real obvious out of the way: The win gives San Francisco the No. 1 seed in the NFC and home-field advantage for the first time since 1997.
It’s obviously a huge advantage for the 49ers to be able to rest at home for the playoffs. Having the road to the Super Bowl go through San Francisco is especially important if one of the teams on the eastern side of the country, especially the Green Bay Packers, have to fly over.
The Niners have a good record at home, losing only to the Seahawks in a Week 10 game without tight end George Kittle (and we saw what a difference that made in Week 17) and during an upset to the Atlanta Falcons in an obvious trap game.
There are no trap games in the playoffs, and the 49ers have a healthy Kittle at their disposal.
With the advantage of a rocking Levi’s Stadium behind them, instead of the hostile atmospheres in Seattle, New Orleans Or Green Bay, beating the Seahawks in Week 17 proved to be a massive advantage for San Francisco.
