I agree, Seattle completely outplayed Denver in all aspects of the game. Their defense is awesome and they always seemed one or two steps ahead of Denver throughout the game. Manning was rattled but he wasn't the only one. The O-line couldn't handle Seattle's pass rush and the Seattle secondary showed why they are the best in the game. Add a couple early turnovers and bad special teams play by Denver and the momentum swung completely in favor of the Seahawks.
There were lots of key plays during that game, not including the turnovers, but I would say Seattle's offensive success on third down, in the first half, really tipped the scales heavily in their favor. Also, their defense completely stopped Denver on third and some key fourth down plays. That was about as one sided a SB game as I can ever recall seeing. It was kind of a disappointment because after so many great playoff contests this post season, the BIG game was decided long before halftime!
Oh, and I really liked Bruno Marz and the RHCP's at halftime. That guy is a very talented young entertainer who writes his own music, can play every instrument (drums, piano/keyboards, guitar, base, harmonica, etc.) and has a three octave vocal range! AND, he can dance like a young James Brown! I was not familiar with his music before last night (other than a couple pop songs on the radio) but I was impressed by his talent. He's like a young Prince, mixed with James Brown, with the vocals of a young Michael Jackson (before he went nuts). It was possibly the best SB halftime performance I have seen in years. Maybe the best ever, IMO.
