Seahawks 20-7 because the lions are from Detroit which is Michigan which is the team up north which never wins anything
Seahawks win 27-17 because I heard an inside rumor that they deflate their footballs, so Russell Wilson has an advantage
Seahawks win 27-13. They have both a superior offense and a superior defense. This isn't a scary game for them.
31-10 Seahawks for the win because they have a great offense and Lions doesn't have a defense to stop them
