NFL Scores Week 2: Breaking Down This Week's Biggest Upsets

Week 2 was even more exciting than Week 1 in the NFL. That may be cliche, but odds are if you took the favorite in any of your picks this week, you were biting your nails all the way down to the wire.

From Miami to Arizona, teams that were supposed to be headed for top 10 selections in next year's draft made a statement to the entire league: If you don't play hard and prepare the right way, you are going to get beat, no matter the team or situation.

That proved true league-wide, and here's a complete breakdown on the three biggest upsets from this weekend's action so far.

Seattle 27, Dallas 7

How It Happened: Seattle bullied Dallas all game

 Dallas was seemingly dominated in every aspect of this football game. Seattle will hit you hard, they will get back up and tell you about it and they took Dallas out of their game plan early on by forcing turnovers and completely taking control of the special teams game.

The running game was nonexistent, and don't let Tony Romo's 250 yards passing fool you, he was out of the pocket and having to make plays because pressure kept coming.

Of course, I would be remiss not to mention that Jason Witten, usually the steadiest of targets, had four drops, two of which might have gone for 30-plus yards.

Either way, Seattle made Dallas look like the same old team we love to bash. It was a dirty game, and it was won in the trenches. Dallas had players going on and off the field via injury or being shaken up all game, and Golden Tate laid out Sean Lee late in the ball game. That play was indicative of the way Seattle played all day.

Arizona 20, New England 18

How It Happened: Arizona made less mistakes than NE

In one of the most unusual games of the season so far, Arizona used their pass rush and a key special teams play to knock off the Pats at home.

Tom Brady was sacked four times, and New England couldn't convert a two-point conversion late in the fourth quarter or a Stephen Gostkowski field goal that would have given them the victory as time winded down.

Give Arizona a lot of credit; Kevin Kolb played well and limited mistakes on offense. However, Arizona should probably be 0-2 after Braylon Edwards' drop in Week 1 and two late mistakes this week. But they have more wins than most of the league, and remain undefeated.

Miami 35, Oakland 13

How It Happened: Ran wild on the ground

Reggie Bush looked like a Heisman Trophy winner, rushing for 172 yards and two TDs as Miami won their home opener. They also didn't turn the ball over, while outgaining Oakland by more than 200 yards on the ground.

After having a nice week defensively against San Diego, Oakland laid an egg as favorites on the road in this one. Poor tackling, no run game to combat Miami's time of possession and being outscored 28-3 in the second half are all characteristics of the Oakland teams of the last several years, and that was evident again Sunday.

Ryan Tannehill had a nice afternoon, and his turnover-free game is going to be key to Miami winning and competing in the AFC East.

Oakland is looking to enter the Matt Barkley sweepstakes, it seems, and will try to keep him in California if they keep putting up performances like this one.
