This was a horrible Super Bowl, the worst I can remember in the last decade. The last bad game that comes to mind was the Ravens vs. the Giants that ended up being a similarly one-sided affair. However, that Giants team didn't have the greatest offense ever so this was even more stunning.
Yes, it seems Seattle might be well on their way to forming the next great dynasty in the NFL. They have another year at least before guys like Russell Wilson want to talk about their contracts. That NFC West is just nasty right now.
