We've already seen some upsets take place this season in the NFL, but which upsets are set to go down in Week 4?
Arizona Cardinals and New York Giants
The Giants are coming off a big win against the Eagles in Week 3. The boys in blue might be feeling great right now, but the Giants are a team traveling to the west coast.
Along with the long travel, the Giants, to me, are just the type of team that can get a huge win one week and then a huge loss the next.
The Cardinals defense hasn't been the most talented bunch in the NFL, but the Giants also aren't the most explosive offense. We did see some nice plays from the Giants in Week 3, but traveling to Arizona won't be easy for Eli Manning and company.
I think the performance of the Cardinals defense and Giants offense will both be very average. However, the Cardinals offense will have a much better week.
Kevin Kolb and Larry Fitzgerald will give their team an edge and find a way to outscore the Giants. This matchup will be a close one, but the Cardinals will come out on top at home.
Detroit Lions and Dallas Cowboys
The Detroit Lions are 3-0 and ranked fourth in the ESPN.com Week 4 NFL Power Rankings. The Lions are a completely different team than they were a couple seasons ago.
The Lions may be on the road this week, but the Dallas Cowboys aren't proving to be the toughest team to beat.
Tony Romo was clearly still sore in Week 3 after suffering a rib injury in Week 2. Add the absence of WR Miles Austin to that and the Cowboys aren't looking very hot.The Washington Redskins nearly defeated the Cowboys in Week 3.
The Lions are a team that can do some serious damage on both sides of the ball. They managed to pull together a huge comeback win against the Minnesota Vikings in Week 3.
True, the Vikings have blown leads in the second half every week, but the Lions still displayed that nasty offense we all know exists. Now that Matt Stafford seems to be staying healthy, he and Calvin Johnson are on their way to being an elite passing combo in the NFL.
On top of this scary offense, the Lions defensive line is practically a brick wall. If the Cowboys' running game comes to a stop, Romo will be forced into putting the team on his back.
Considering Romo still has an injury that may be sore again this week, he doesn't need that kind of pressure. Romo also has Ndamukong Suh coming after him.
The Lions might be 4-0 after this week, and I don't think it will be so surprising if they are.
Oakland Raiders and New England Patriots
The Patriots have already been victims of an upset this season. Last week, Tom Brady and company went down against the Buffalo Bills. This week they could be in for another upset loss in Week 4 against the Oakland Raiders.
We all know the Patriots have a potent offense with Tom Brady running the show. However, the Patriots performance against the Bills in Week 3 was rather weak. Brady threw four interceptions and the Patriots defense continued their struggles.
Not all of the four interceptions can be blamed on Brady, but they still happened. Whether the ball is bouncing off a receiver's hands or being batted by the defensive line, you still have to fix the problem.
The Patriots defense allowed the Bills to net a total of 448 yards. The Bills got these yards while overcoming a 21-0 deficit.
The Patriots defense also allowed a game-winning drive by the Bills at the end of the fourth quarter.
The Patriots have a tough week ahead of them. Taking a trip to the West Coast to play the Raiders, a team that has proved they aren't a pushover anymore, won't be easy.
Along with a defense that is putting up a legitimate fight each week, the Raiders have a strong running game with Darren McFadden in the backfield. I just have a good feeling about the Raiders this week.
I obviously don't expect Brady to have four interceptions again. However, I think the Raiders just might be able to take advantage of the long and depressing week the Patriots and their struggling defense are having.
