Entering Week 6 there were three undefeated teams in the NFL in the New Orleans Saints, Denver Broncos, and Kansas City Chiefs. As the week ended, only the Broncos and Chiefs remain in that category, and they just happen to play in the same division.

Along with the undefeated teams, the list of the winless teams in the NFL also shrunk in Week 6. The Pittsburgh Steelers snatched up their first win of the season.

With the ups and downs consistently trending every week, there are exciting moments in every NFL game. With that being said, here is the best and worst of Week 6 in the NFL.

Steelers win their first game

The Steelers faced off against the New York Jets Sunday in a game in which Pittsburgh was in desperate need of its first win of the season. Quarterback Ben Roethlisberger threw for 264 yards and a touchdown to lead the Steelers to victory.

Pittsburgh's defensive end Brett Keisel believes that this first win could be the start of something great.

"We're not going to quit," Keisel told ESPN. "Obviously, it wasn't the start we wanted, but the men in this locker room believe there's a chance that something great could come out of this if we all work toward it."

With the win, the Steelers move to 1-4, and will have a chance to continue their road to greatness Sunday when they host the defending Super Bowl champion Baltimore Ravens.

Texans get crushed by Rams, fans cheer when Schaub gets injured

It is never a pretty sight when an athlete goes down with an injury. When Houston Texans' quarterback Matt Schaub went down with an ankle injury against the St Louis Rams, the sound of cheering was the last thing you'd expect to hear. Nevertheless, the sound of cheering could be heard throughout the Houston crowd as Schaub clutched his leg.

T.J. Yates replaced Schaub, but things only got worse. Yates threw two interceptions. The Texans turned the ball over four times in the game in the 38-13 loss.

While Schaub could return as early as this week, many changes need to take place for this disappointing Houston (2-4) team.

Chiefs defense dominates, move to 6-0

The Kansas City Chiefs continue to impress football fans everywhere. While ending the 2012 season with the worst record in the NFL, the Chiefs have managed to remain as one of the two undefeated teams left in the NFL.

Sunday, Kansas City faced the Oakland Raiders in a game where the Chiefs owned the game on both sides of the ball. The Chiefs' defense managed to sack Oakland quarterback Terrelle Pryor 10 times, pick off three interceptions, and score a touchdown. Running back Jamaal Charles also ran for 78 yards and two touchdowns. When all was said and done, the Chiefs defeated the Raiders, 24-7.

With the win, the Chiefs move to 6-0 and look to extend their streak Sunday against the decimated Texans.

Buccaneers defense gets scorched by Eagles

Entering the season, the expectations were high for the Tampa Bay Buccaneers. They had a franchise quarterback in Josh Freeman, a superstar receiver in Vincent Jackson, a future star in Doug Martin, and a promising defense. It looked as thought it was going to be a great season.

Now at this point in the season, everything has fallen apart. The Buccaneers cut Freeman, Martin isn't having the type of season everyone hoped for, and the defense is just awful. Tampa Bay hasn't won a game all season.

Sunday's matchup had Tampa Bay facing the Philadelphia Eagles who were missing their starting quarterback Michael Vick. The Eagles had no problems however. The Buccaneers defense couldn't stop back up quarterback Nick Foles. Foles threw for 296 yards and three touchdowns, and ran for another touchdown. Philadelphia running back LeSean McCoy also ran for 116 yards in the 31-20 win.

With the loss, the Buccaneers are now 0-5 and they have some big changes that need to be made before heading to Atlanta to face the Falcons.

Tom Brady throws last-second TD pass, Pats hand Saints first loss

With 1:13 left in the game, New England quarterback Tom Brady took the field trailing the New Orleans Saints by four points. Many of the New England fans had already left the game, and were making their way to their vehicles. Brady then led the Patriots on a 70-yard drive in which he picked apart the Saints' defense, including two passes to former BYU wide receiver Austin Collie.

On the final play of the drive, Brady threw a strike to Kenbrell Thompkins for a touchdown with only five seconds remaining. Brady ended the game with 269 yards and a touchdown in the 30-27 win, proving once again why he is considered one of the greatest quarterbacks of all-time.

With the win, the Patriots improve to 5-1 on the season, while handing the Saints their first loss of the season.

Jimmy Graham injures leg

On top of the heart-breaking loss to New England, the Saints have yet another thing to worry about. Going in to Week 6, Saints' tight end Jimmy Graham had recorded his fourth straight 100-yard receiving yard game, which ties an NFL record for a tight end. In Week 6 however, Graham was rather quiet up until he injured his leg. With such an important target hobbled, quarterback Drew Brees will have to look to other targets to pull their production weight.

Luckily for New Orleans, it has a bye in Week 7, a week in which it hopes Graham will have time to heal.

Cam Newton scores four touchdowns against the Vikings

The Carolina Panthers suited up against the Minnesota Vikings in Week 6, in a match up that will be remembered for being a game in which Panthers' quarterback Cam Newton was simply unstoppable. Newton threw for 242 yards, three touchdowns and ran another touchdown in to lead the Panthers to a 35-10 victory over the Vikings.

When Newton's passes are on target and when he is picking up yards on the ground, the Panthers are tough to stop. Look for Newton to try and lead the Panthers to another victory against the Rams in Week 7.

Eli Manning throws three interceptions, Giants fall to 0-6

Only two years removed from a Super Bowl victory, and the New York Giants are already off to one of their worst starts in team history. Instead of looking like a former contender, the Giants simply look like a bottom-feeder in a lousy division. No matter what adjustments they make, every week they turn the ball over and lose football games.

Two-time Super Bowl MVP Eli Manning looks like a shell of his former self. He leads the league in interceptions with 15, and can't seem to get any protection from his offensive line. Over the years, Manning has developed a reputation for being the most clutch quarterback in the league. Over the past two seasons, his fourth-quarter quarterback rating was at 76.6. This year? Three. Yes, three.

Thursday, the Giants faced the Chicago Bears. Giants' running back Brandon Jacobs had a great game with 106 yards and two touchdowns. However, Manning couldn't help but throw three interceptions that ended up being the difference-maker in the 27-21 loss.

With the loss, the Giants fall to 0-6, a record which no one could have predicted. If Manning can't find his former self, he may just find himself on the bench by the end of the season.

Andy Dalton lights up Bills' defense through the air

The Cincinnati Bengals went head-to-head with the Buffalo Bills Sunday, and it was a nail-biter. In overtime, after both teams had punted, it was a field-goal by Mike Nugent that ended up sealing the 27-24 victory for the Bengals.

Cincinnati quarterback Andy Dalton threw for 337 yards and three touchdowns to help the Bengals improve to 4-2, the best record in their division. After taking much heat for their early losses this season, Dalton hopes that this win will bring positive feedback to the team.

"It shows what we can do on offense," Dalton told ESPN. "Hopefully, there will be some positive stuff written about us."

If Dalton continues to have games like that, then rest assured, positive things will continue to be written about the Bengals.

RG3, Redskins get dismantled by Cowboys

After their bye week, many hoped that the Washington Redskins would have figured out what was wrong with their team and make adjustments to get back on the same path they were last season. Sadly, the Redskins seemed to be every bit the same team they were earlier this season.

The Redskins played the Dallas Cowboys Sunday in a game in which neither quarterback could find a groove. Washington quarterback Robert Griffin III threw for 246, no touchdowns, and one interception, whereas Dallas quarterback Tony Romo threw for 170 yards with a touchdown and an interception.

The difference was the Redskins' poor special teams play, which allowed Cowboys' returner Dwayne Harris to rack up 222 total return yards including one touchdown. When all was said and done, the Cowboys topped the Redskins 31-16.

With the loss, the Redskins move to 1-4 on the season, which puts them at second to last in their division, just above the 0-5 Giants. Washington better change up something before hosting the Chicago Bears on Sunday.

With both the groups of undefeated and winless teams shrinking more and more with every week, there are certainly some big things in store. From Peyton Manning returning to Indiana to face his former team, to the intense Cowboys vs. Eagles, Week 7 in the NFL looks to live up to every bit of the hype.
