The 49ers face the Seahawks this week up at CenturyLink Field. I'd love to see an upset up there, but it's going to be a tough one. For fantasy purposes, 49ers-Seahawks games are not really the most appetizing of matchups. Marshawn Lynch is really the only player on either team you could start in a fantasy league with some degree of confidence.

If the 49ers do figure out a way to spring an upset, it would likely come in large part due to a big performance from the defense. You can get the 49ers defense for $4,900, which is right in the middle of the pack. Most expensive is Seahawks at $5,500 and least expensive is the Falcons at $4,500.

On the offensive side of the ball, Colin Kaepernick and Frank Gore would probably be the two guys who would need to go off for a 49ers upset. Kap can now be had for a fairly inexpensive $6,800, while Gore is down to $5,300. Both are bargains if you want to add 49ers that might impact this game. You can also get Anquan Boldin at $6,900.
