As is the case with every NFL season in history, as the weeks go on, the number of undefeated teams remaining in the league shrink more and more.
Week seven was no different.
The Denver Broncos lost their first game of the season leaving the Kansas City Chiefs as the only undefeated team left in the NFL.
The same case applies to the winless teams in the NFL. Normally as the season progresses, the list of winless teams shortens. With the New York Giants winning their first game of the season Monday, the Jacksonville Jaguars and Tampa Bay Buccaneers are the last two winless teams.
With everything from intriguing match-ups to season-ending injuries, week seven had a bit of everything to make football fans cheer and jeer.
With that said, here are the best and worst of week seven in the NFL.

Alex Smith, Andy Reid & Chiefs stand alone on top
After winning only two games in 2012 and finishing with the worst record in the league, the Chiefs were in desperate need of a turn around. After naming Andy Reid as head coach and trading for quarterback Alex Smith, the Chiefs definitely seemed to be taking steps in the right direction.
What nobody expected is that 2012's worst NFL team is currently 2013's best. With a 17-16 win Sunday against the Houston Texans, Kansas City improved to 7-0. Smith's game-managing abilities were on full display as he threw for 240 yards. He also displayed his ability to run the ball with a rushing touchdown as well.
The Chiefs suit up again Sunday with a home game against the Cleveland Browns. Barring something catastrophic, expect Smith to lead the Chiefs to 8-0.
The Rams lose Sam Bradford for the season
The St. Louis Rams suffered a horrible loss in their hopeful season Sunday. Quarterback Sam Bradford tore his ACL and miss the rest of the season. This injury is a big blow to the Rams' offense because the Heisman Trophy winner was tied for fifth in the NFL in passing touchdowns.
There are rumors of a possible trade with Minnesota for quarterback Matt Cassell, which would give the Rams a chance of at least competing once again for a playoff spot. Whatever St. Louis ends up doing, it needs to do it fast. The Rams host the Seattle Seahawks on Monday Night Football.
Andrew Luck, Colts spoil Peyton Manning's return to Indianapolis
Denver Broncos' quarterback Peyton Manning returned to Indianapolis Sunday night to face his former team, the Colts, in one of the most anticipated match-ups of the year. With Colts' owner Jim Irsay's controversial comments on Manning's years with Indianapolis and the endless talk of Colts' quarterback Andrew Luck becoming the next Peyton Manning, the battle between the two teams had emotions running high.
Before the game started, the Indianapolis crowd gave Manning a standing ovation, showing appreciation for all he did for the Colts' organization. As the spotlight was on Manning, he removed his helmet and acknowledged the fans that supported him for so many years. It was a special moment for football fans everywhere.
But that moment was short-lived as the spotlight shifted to Luck. He put on a dominating performance in handing the Broncos their first loss of the season. Luck threw for 228 yards and three touchdowns and ran for an extra score to lead the Colts to the 39-33 win. Luck's composure and poise was extremely impressive, and made it hard to doubt that he has the ability to be one of the greatest to ever play the game.
At the beginning of the season, the San Francisco 49ers, Seattle Seahawks, and Denver Broncos were the most popular Super Bowl picks for this season. So far, Luck has led the Colts to wins over each one of them. It's hard to not consider Indianapolis as a Super Bowl contender with such convincing wins. With the win, they improve to 5-2, and are fully confident in their franchise quarterback.
Eagles' quarterback issues reach critical point, lose ninth straight home game
In the off-season, the Eagles' quarterback battle between Michael Vick and Nick Foles was widely publicized. In the end, Vick was named the starter. Since then, much as changed. After losing Vick to a hamstring injury in week five against the New York Giants, the Eagles decided to move to their second-string quarterback. Foles played an extremely impressive game against the Buccaneers in week six, which caused Eagles fans to gain confidence in his abilities.
The Buccaneers, however, have not won a game this year, so Foles' performance against Tampa Bay is hardly a reliable measuring stick in determining his ability.
Eagles fans would learn this the hard way in week seven.
Foles played absolutely terrible Sunday against the Dallas Cowboys, completing 11-of-29 passes for 80 yards before leaving the game with a concussion. Foles missed wide-open receivers all game, and just seemed as though his nerves were getting the best of him.
After Foles left to the locker room, rookie quarterback Matt Barkley took his place. Although Barkley threw for more yards in part of the fourth quarter than Foles did for the game, Barkley ended with three interceptions on three drives. Dallas beat Philadelphia, 17-3.
Their performances made it crystal clear that there is still no quarterback controversy in Philadelphia. The job is Vick's when he is healthy.
While Vick could be back as early as Sunday, Philadelphia coach Chip Kelly has made it clear that they will wait for him to be completely healthy before starting him. If cleared to play, it is expected that Vick will get the start.
With the loss, the Eagles set a franchise record with nine consecutive home losses. They hope to break that streak Sunday against the 1-6 Giants.
Aaron Rodgers has MVP game against Browns
After a career-long three straight games with only one touchdown pass in each, Green Bay Packers quarterback Aaron Rodgers shook of his slump in week seven and was back in top form in the 31-13 win over the Cleveland Browns. Rodgers threw for 260 yards and three touchdowns to three separate receivers, and was near flawless in every aspect of his game.
His play reminded everyone why he is arguably the best quarterback in the league. When he is on the field, the Packers always have a shot at winning the game.
Expect Rodgers to come out with a big night Sunday in the rivalry game against the Minnesota Vikings.
Bears lose two leaders, drop game to Washington
Sunday's match-up between the Washington Redskins and the Chicago Bears was a tight one, in which the Redskins made plays late to come away with the 45-41 win.
Other than losing their third game this year, the Bears have yet something else to be upset about. Quarterback Jay Cutler suffered a groin tear and linebacker Lance Briggs suffered a shoulder injury. Both players are leaders and both will miss 4-6 weeks.
Without Cutler and Briggs, the Bears look to be in trouble as they head into their bye week, and their championship hopes seem to be disappearing before their eyes. If Chicago doesn't make the necessary adjustments, expect them to have a long night in week nine against the Packers.
Kaepernick is flawless against Titans
In week seven, the 49ers matched up against the Tennessee Titans in a game which San Francisco dominated for most of the time. The Niners led 24-0 before the Titans then made a fourth-quarter run to make the final score 31-17 for the 49ers.
San Francisco running back Frank Gore ran for 70 yards and two touchdowns, while quarterback Colin Kaepernick completed 13-of-21 passes for 199 yards, and ran for 68 yards and a touchdown. Kaepernick had 99.0 quarterback rating, which is the best by any quarterback in a game this season.
If the 49ers continue to punish their opponents on both the ground and through the air, expect them to continue to be a popular Super Bowl pick this year.
Defending MVP Adrian Peterson has worst game in two years
Monday night was a night to forget for the defending MVP Adrian Peterson.
Coming into the game, the Vikings had only one win on the season and the Giants were winless. Peterson, who averages around 80 rushing yards a game, ran the ball 13 times for a grand total of 28 yards in the Vikings' 23-7 loss. The 28 total yards marks the lowest total Peterson has had in a game since 2011.
With a terrible passing game and a lacking run game, the Vikings need some sort of spark before facing the Packers Sunday night.
Robert Griffin III, Redskins secure second win of the season
After an 0-3 start and quarterback Robert Griffin III looking very rusty, things didn't look good for the Washington Redskins. But after week seven, Washington remarkably find themselves only two games behind the Cowboys for the NFC East division lead.
The Redskins beat the Bears in a shootout, 45-41. Griffin threw for 298 yards and two touchdowns and ran for 84 yards in the win. He looked much better than in prior weeks and seemed to be the same player that turned the Redskins around last year in bringing them the division title.
Griffin's ability to run has been a big threat since he came in to the league, but his hesitancy as of late has cost Washington a big part of its strategy. With the 84 rushing yards in week seven, it seems the running threat is back.
As Washington continues to improve, it faces a true test on Sunday as it heads to Denver to face revenge-seeking Manning and the Broncos.
The Jaguars' season can't get worse
The Jacksonville Jaguars are just awful. No matter what adjustments or schemes they make every week, it completely backfires. They are widely considered the worst team in the NFL and don't seem to be trying to do anything to change that.
The Jaguars lost to San Diego, 24-6, Sunday to fall to 0-7.
Just two years removed from leading the league in rushing by more than 200 yards, Jacksonville running back Maurice Jones-Drew, who has been fighting a high ankle sprain all year, appears to have just lost his touch. He has only 316 yards on 103 carries this year, giving him the worst attempt-to-yards ratio among starting running backs in the league.
Unless Jones-Drew performs at his highest possible level, assume the Jaguars to drop to 0-8 Sunday against the 49ers.
With rivalry games between the Eagles and Giants, and Packers and Giants, as well as RGIII facing off against Manning, week eight looks to be every bit as compelling as week seven.
With each compelling week comes many great moments and several terrible ones. Stay tuned.
