The Seahawks have the luxury of being at home in CenturyLink Field for the contest, where they beat the 49ers, 29-3, in Week 2. All of that might be why Seattle is favored by 3.5 points over the defending NFC champions, according to OddsShark.com.The over/under is 39.
San Francisco has won eight consecutive games, the longest current streak of any team in the NFL. Of those victories, one of them came over the Seahawks, back in Week 14 at Candlestick Park. In that game, Frank Gore propelled the 49ers to victory by rushing for 110 yards.
Should the 49ers find a way to win in arguably the NFL's toughest road environment, it would be their seventh Super Bowl appearance, the second-most in league history.
