Every NFL season brings its share of excitement, disappointment and surprises - this season has brought its share already in the first three weeks.

As the season wears on however, the following five win-less teams will fight to stay relevant in an ever-changing league.

New York Giants

Clearly the biggest disappointment so far this season has been the New York Giants.

After their crushing 38-0 defeat to the Carolina Panthers, things have moved to a dire situation for the Giants.

At the rate that they are going, the Giants' defence will give up on average 38 points per game, but the offence of the Giants is a completely different story.

Quarterback Eli Manning being sacked 11 times in three games. To say that the offensive line is struggling is a major understatement.

Things don't look to be so bright for the Giants either as they travel to Arrowhead Stadium, the home of the undefeated Kansas City Chiefs on Sunday.

Minnesota Vikings

After handing last Sunday's game to the Cleveland Browns, the Vikings find themselves at 0-3 on the season.

The shortcomings of the Vikings start at the quarterback position. Christian Ponder has struggled mightily this season so far after throwing five interceptions and being sacked 10 times.

The Vikings face the struggling Pittsburgh Steelers in London this Sunday. In order to leave the UK with their first win, the Vikings must contain the Steelers offence.

As battered as the Steelers may be, they pose a tough task for the Vikings this weekend.

Tampa Bay Buccaneers

The Buccaneers are looking to salvage their 0-3 season by benching quarterback Josh Freeman.

Freeman struggled to help the offence score in the team's first three games. The Buccaneers are going with rookie Mike Glennon against the Arizona Cardinals who are 1-2 on the season.

Depending on the success of Glennon, the Buccaneers have a shot at rescuing their season and pulling closer to their division rivals.

The defence of the Buccaneers is the best of the 0-3 teams. Don't be surprised if the Bucs walk away on Sunday with their first win of the season.

Pittsburgh Steelers

The Steelers have the best chance to save their season of the five 0-3 teams.

They have been ravaged by injuries and are starting to get some of their players back on the field.

Rookie running-back, Le'Veon Bell will be making his debut for the team in London this week - Bell has one of the brightest future's of the young running backs in the NFL.

With his return, the Steelers have regained their running threat. The Steelers will likely also have tight end Heath Miller in London after sustaining a minor knee injury. 

The defence of the Steelers is the biggest problem. With the loss of many veterans due to free agency and injuries, the 'Steel Curtain' is looking a bit rusty.

The key against the Minnesota Vikings will be whether or not they can contain running back Adrian Peterson. 

Jacksonville Jaguars

The Jaguars have too many missing pieces to fill in order to be a legitimate contender this season - the situation in Jacksonville is pretty dire.

Chad Henne has been mediocre considering he has nothing to work with. Running-back, Mercedes Lewis returns from an injury which will definitely help the running game. 

The Jaguars will play the Indianapolis Colts this weekend. The Colts are coming off of an incredible win over the San Francisco 49ers last week. The Jaguars will have to pull off a miracle to win a handful of games this season.
