The phrase "Any given Sunday" is quite true in the NFL, and there are a few teams that are going to learn that the hard way in Week 4 of the season.
The upset of the week had to be the Indianapolis Colts taking down the San Francisco 49ers in Week 3. The 49ers were already coming off of a loss to the Seattle Seahawks, and many thought they were going to take out their frustrations on a banged up Colts team. Instead, the Colts took everyone by surprise, pulling off the big win.
This week, there are a few teams that have the opportunity to do the same thing.
New York Jets at Tennessee Titans
That offense may not be the prettiest, but the Jets defense is the real deal.
How many wins will the Jets have by the end of the regular season?
The Jets are coming off a thrilling 27-20 win over the Buffalo Bills, with Geno Smith throwing for 331 yards along with two touchdowns and two interceptions. As bad as the offense looked through two weeks, it showed signs of being decent this past week. The ground game has been productive with Bilal Powell running for 226 yards and a touchdown up to this point.
The defense is what's been so impressive so far. Opposing teams are putting up less than 16 points per game, and the Jets are third in the NFL allowing just 270 yards of offense per game.
The Tennessee Titans are 2-1, but their passing game is suspect. Jake Locker has 572 yards and three touchdowns up to this point, but he's also thrown zero interceptions. Chris Johnson is off to a slow start, averaging just 3.7 yards per carry.
The Jets' defense is going to keep them in this game, just like they did for the other three games this season. It may not be the prettiest win, but the Jets are going to find a way to get it done this week and start the season with a 3-1 record.
Prediction: Jets 20, Titans, 17
Tampa Bay Buccaneers vs. Arizona Cardinals
The Buccaneers have not looked good to start the season, but that mentality is going to change against the Arizona Cardinals, even if it's only for a week.
Adam Schefter reported the news that the Bucs had decided to bench quarterback Josh Freeman and replace him with rookie Mike Glennon.

While it may be a risky move, I think it's going to make this offense better.
To be honest, it can't get much worse. Freeman only threw for 571 yards and two scores through three games while throwing three interceptions.
Meanwhile, the Cardinals have allowed an average of 297 yards through the air and just over 26 points per game. Despite the arrival of Carson Palmer, the offense hasn't looked very impressive so far.
The mentality of the team with Freeman under center wasn't a positive one, but with a new quarterback playing on offense, it should motivate the rest of the team to step it up, although that motivation likely won't last much longer than a couple of weeks.
Prediction: Buccaneers 24, Cardinals 20
Detroit Lions vs. Chicago Bears
The Chicago Bears are looking like one of the top teams in football, but the Lions are going to have something to say about that this week.
Yes, the Bears are 3-0, but two of those wins have been against the Minnesota Vikings and Pittsburgh Steelers. Even worse, the Bears nearly lost to the Vikings, giving up 30 points to a team with an incredibly questionable quarterback in Christian Ponder.
The quarterback position certainly isn't a question mark for the Lions, who have Matthew Stafford. The former Georgia Bulldog has had a strong start to the season, already throwing for 1,020 yards and six touchdowns with just two interceptions.
The Lions offense should be even better this week as it appears that Reggie Bush could be back in time to go up against the Bears, according to Marc Sessler from NFL.com.
As good as the Bears have looked so far, the Lions offense should make this one entertaining game to watch, with Detroit winning in a shootout.
Prediction: Lions 38, Bears 35
