The Minnesota Vikings are 9-0 at the Metrodome after devastating a Dallas Cowboys team that many chose to go all the way to the Super Bowl.

Dallas went on a four-game-win-streak which was accomplished by putting a dominating defense on the field, keeping turnovers to a minimum and the run game getting a jump start thanks to Felix Jones before the showdown with the Vikings on Sunday afternoon.

None of those winning qualities were present in the 34-3 loss to the Vikings. 

Tony Romo, who's done a spectacular job of protecting the football throughout the second half of the season, threw an interception and lost two fumbles. 

It would be easy to pin Romo as the scapegoat based on his poor numbers but the Cowboys offensive problems were much deeper than the quarterback position. 

The offensive line was the root of the Cowboys offensive problems.

The Cowboys O-line wasn't faring well against a strong rush from the Vikings defensive line when Flozell Adams was in the game.  Once Adams was sidelined with a strained left calf, the offensive line crumbled, putting up an absolutely embarrassing performance with four different Vikings defensive linemen getting one or more sacks. 

Vikings defensive end Ray Edwards almost reached half of his regular season sack total in a single game against a shaky Cowboys offensive line. 

As strong as the urge is to dump the Cowboys season-ending debacle on Romo, it isn't fair considering he couldn't even complete a three-step-drop without a Vikings linebacker burying a helmet in his chest. 

Lets start with the Cowboys offensive coordinator and once proclaimed 'head coach in waiting,' Jason Garrett.  Who also happens to be the highest-paid assistant in the league at $3 million per year. 

Garrett shined at times this season but has also looked clueless, as he did against the Vikings. 

Marion Barber, who's had injury problems all season, bizarrely got the start over Felix Jones coming off the game of his life just a week earlier against the Eagles in the first round of the playoffs.

It's mind-boggling that the Cowboys did not give Jones the start, especially knowing how important it was to get on the board early against a fierce Vikings defensive line. 

Garrett and Co. were instead adamant on giving Barber the nod, assumably because of the boatloads of money the Cowboys are pouring in Barber's pockets.   

The decision resulted in the Cowboys offense coming to a screeching halt and being forced to punt the football on back-to-back offensive possessions and it was a trend that continued throughout the entire game. 

Barber finished the game with eight carries for 14 yards, averaging just 1.8 yards-per carry. 

As poorly as Barber performed, there is still plenty of blame to go around, particularly with the receiving core. 

Tight end Jason Whitten led all receivers with 10 receptions for 98 yards, which was a shock to no one as he's put up solid numbers all season. 

Wide Receiver Miles Austin had just four catches for 34 yards and was never able to make that big play downfield, which he's done several times this year. 

Austin's numbers were spectacular, however, when compared to what's been the Cowboys most disappointing acquisition in years. 

Self-proclaimed number one receiver, Roy Williams, had back-to-back embarrassing seasons with the 2009 season being worse than the previous year.

In the Cowboys biggest game of the season against the Vikings, Williams had no yards and not a single reception. 

The Cowboys gave up four draft picks, are paying Williams $9 million per-year over five years, with more than $20 million guaranteed, and the wideout produced just 596 receiving yards on the season. 

Those numbers are what you'd expect from a number three wide receiver like Patrick Crayton, who had 26 yards more receiving yards than Williams did on the season.  

The Cowboys fans and media alike gave Williams a break last season, as he'd only played 10 games with Dallas and didn't have a chance to go through training camp, but after seeing his production this season, it's clear there are other issues. 

Just as the stock of Miles Austin began to soar, Williams told reporters that Romo wasn't throwing him accurate passes and that Williams had to stretch and dive to catch the football. 

Roy Williams runs poor routes, lacks explosiveness and hasn't had a strong season since 2006 with the Detroit Lions. 

As much as Williams has struggled in Dallas, it is ultimately up to Jason Garrett to somehow get him involved in the offense. 

Williams was only targeted one time against the Vikings. 

At some point, when nothing else seems to be working, it is Garrett's responsibility to work around Williams shortcomings and put the ball in his hands whether it be a screen-pass, a reverse or some type of trick play.  

But as bad as Roy Williams career seems to be headed and as much as it stings the Cowboys front office to burn $45 million, the offensive line was an absolute killer for the Romo and the Cowboys offense. 

Romo was sacked a season-high six times and hit another 10 times. 

The Cowboys offensive line coach, Hudson Houck failed in giving Romo more than a split second in the pocket without getting hammered.  And if Houck didn't step up to the plate, it's even more surprising that Garrett or even head coach Wade Phillips didn't intervene to solve the painful problem. 

The Cowboys haven't been held to three points since 2003 against the New England Patriots. 

Looking towards the future of the Cowboys, the team has played better each season since 2007 and several players had breakout years. 

For the defense, corner back Mike Jenkins was fighting for a starting spot at the beginning of the season but quickly improved into a lockdown corner in only his second season. 

Safety Gerald Sensabaugh also played very well, especially towards mid-season and will be key to the Cowboys future if he can continue in his progression. 

On the offensive side of the ball, Miles Austin had a phenomenal 1,320 yard, 11 touchdown season, ranking third amongst 2009 leading receivers.  Austin lead the league, averaging 16.3 yards-per-reception for receivers with more than 80 catches. 

Felix Jones saw his stock rise after an explosive 148 yard performance against the Eagles in the first round of the playoffs.  Jones proved that he can be a physical back to compliment his lighting-fast speed but was greatly underutilized for most of the season. 

It seems as though the Cowboys will not cut Williams as many Dallas fans had hoped but if he has another season similar to the last two, his acquisition will go down as one of the worst in NFL history.
