I'm wondering why Seattle is a 10.5 point favorite over SF. Seattle is averaging 7.5 points a game so far this season. Their offensive line is terrible. I can see Seattle winning the game, but don't see how they will cover the 10.5. I'm not sure they can even score much more than 10 points. To cover, Seattle would practically have to shut out SF completely. Am I way off on taking SF + 10.5.
