The Seattle Seahawks and the San Francisco 49ers face off on Sunday night football with the NFC West on the line. The Seahawks are dealing with some key injuries but they still have a very good chance to come away with a victory. Let's breakdown four reasons the Seahawks will come away with a win.

4. Home field advantage

CenturyLink Field isn't a place that opposing teams want to come to play football, especially close to playoff games. On the season the Seahawks are only 4-3 at home this year, but it's different in big games, especially at night.

The 49ers aren't going to be able to think it's going to be to so loud. There probably should be a few false starts or delay of games caused by Seahawks fans.

3. Marshawn Lynch

There are still some big questions about how big of an impact Marshawn Lynch is going to have on this game but he should give the team a big emotional boost. This is a guy that is loved inside the locker room and the fans are going to be extra fired up with Lynch back.

It's hard to imagine he is going to get more than 10 or 15 carries but if he can get 40 or 50 yards that is a big boost. If nothing else the 49ers still have to respect Lynch's running abilities. They might not have to load the box but they can't completely ignore him or he will break off one of those long ones.

2. The Seahawks defense is getting healthy

The Seahawks are banged up on offense, but the defense is getting healthy and that is a big deal for the 49ers. Jadeveon Clowney and Shaquill Griffen are back and that is important because they both anchor the defense. Pete Carroll said it best talking about how important it is that they are back.

“That’s huge,” Seahawks coach Pete Carroll said via the Seattle Seahawks team website. “It’s a huge deal. I mean, our top cover guy and a top rusher. That’s a big deal. It’s great to have those guys back out.”

Clowney might only be 80 or 90 percent, but he is still a key piece even not being 100 percent. Clowney is going to invite double teams which means even if he isn't in the backfield, others will be because the focus is going to be on him.

1. Russell Wilson

Russell Wilson is one of the best quarterbacks in football, and since coming into the league he has been elite in primetime games. Wilson is 16-2 in prime time games and is 31-7 after a loss.

If this game is close in the 4th quarter that is what Wilson is built for. He is going to make key throws and will be the difference in this game. On the season Wilson has completed 66.4 percent of his passes for 3,877 yards, 29 touchdowns,  and five interceptions.

With so many questions surrounding the running game Wilson might need to take a bigger role and that should be no problem. Look for Wilson to help the team clinch another NFC West title.
