The New York Giants defense will score big in fantasy football Week 4.

After a week in which the Giants scored 16 fantasy points, owners must be licking their chops with the Giants playing the Philadelphia Eagles.

With 10 turnovers in the first three weeks of the season, Michael Vick has helped opposing defenses rack up tons of fantasy points.

The Giants have a fearsome front-four that includes Justin Tuck and Jason Pierre-Paul. Throw in their secondary of Prince Amukamara, Antrel Rolle, Kenny Phillips and Corey Webster, and you have the makings for a long day for Vick.

Vick has consistently made bad decisions with the football this year. So much so that head coach Andy Reid might consider a change.

According to Jeff McClain of the Philadelphia Enquirer, "Right now, we're with Michael and that's what we're doing," Reid said Monday after the Eagles' 27-6 loss at Arizona. "We'll evaluate it as we go."

It's getting bad in Philadelphia and opposing defenses are going to feast on Vick. That makes the Giants a great start in Week 4.

If the Giants don't come out of this game with at least 12 or 13 points, many will be surprised.

However, the Giants aren't the only defense that will score big this week.

San Francisco 49ers

Forget the hiccup the 49ers had last week against the Minnesota Vikings. The 49ers get the New York Jets this week and it couldn't come at a better time. 

The 49ers defense has only scored 13 points this year, but that's not going to last long.

The Jets come in with good performances against mediocre Miami Dolphin and Buffalo Bill teams. Sandwiched in between those games were the Pittsburgh Steelers, who held the Jets to 10 points.

Mark Sanchez struggled to throw the ball with only 138 yards passing, while the leading rusher was Bilal Powell with 33 yards.

As the Jets showed in preseason and as they showed against the Steelers, their offense is no match for a good NFL defense. That's what the 49ers are.

With one of the stronger run defenses in the NFL (141 yards per game), San Francisco's weakness is in the secondary. Luckily for them, New York can't do either very well.

As Sanchez will struggle again, the chants of (Tim) "Tebow" will begin to come in New York.

Baltimore Ravens

Any time the Cleveland Browns play a team this year, opposing defenses know their fantasy stats are going to pile up. 

The best thing the Browns have going for them is running back Trent Richardson. However, Richardson can't get going with only 175 yards rushing this year.

Then there's quarterback Brandon Weeden, who has no real threat to throw to at receiver.

The Browns don't have an identity on offense, which can make it hard to plan for. But, six interceptions tell part of the story when Weeden tries to form an identity.

The Ravens have always had a stout defense. Since the 2008 season, Baltimore has finished outside of the top three in total defense one time.

Ray Lewis is the key behind that, and he'll be the key behind Sunday's effort against the Browns.

With no real identity, the Browns will be no match for the Ravens.
