NFL Predictions Week 4: Which Underdogs Have Best Upset Shots?

Being the underdog is always fun, because you have a great opportunity to prove the skeptics wrong.

And there's nothing more satisfying in sports than knowing you're the better team as opposed to the so-called favorites.

That being said, here are two underdogs that have the best shot at pulling off the upset in Week 4.

Carolina Panthers (Underdog) at Chicago Bears (Favorite) -6.5

Through the Panthers' first two games, rookie QB Cam Newton tossed for over 400 yards and Carolina lost each contest by just one TD.

Last week, Carolina finally got the much needed W, and have a lot of confidence heading into Week 4.

Their opponent are the Chicago Bears who, although they have lost to two good teams in Green Bay and New Orleans, are a vulnerable bunch.

QB Jay Cutler continues to struggle with consistency and the rushing attack is suffering.

In addition, the pass defense is once again their weakest link, but the rush defense isn't as good as it was in 2010, either.

Regardless of whether you're a betting person or not, the Carolina Panthers have a legitimate shot at winning this football game.

Chicago will give up the passing yards, the question is whether Jay Cutler can keep up with Cam Newton like Kevin Kolb and Aaron Rodgers did.

Yes, Chicago's offensive coordinator, Mike Martz, is one of the best in the game, but it's taking Cutler longer to develop than Kurt Warner and Mark Bulger.

In the end, Carolina upsets the Bears on the road thanks to an excellent passing game, while Chicago's offense fails to keep pace.

Oakland Raiders (Underdog) vs New England Patriots (Favorite) -4.5

Although the Patriots aren't going against a stud QB like Ryan Fitzpatrick this week, Oakland's Jason Campbell is doing a fine job managing games.

RB Darren McFadden is currently the NFL's leading rusher, and rightfully so, as the Raiders rank No. 1 in rushing offense.

This week it's going to be very difficult for the Oakland defense to slow down an angry Tom Brady, but keeping him off the field will limit his opportunities, thus giving the Silver and Black the advantage.

The only reason the Pats' rush defense isn't ranked lower is because the pass defense allows 377 yards per game.

That's good for worst in the league, so there's no reason to run the ball when you can easily rack up points faster through the air.

Well, Campbell isn't that kind of QB in Oakland, plus the Raiders are playing old-school football by winning on the ground.

New England has trouble slowing down McFadden, opening up the passing game just enough for Campbell to be effective.

Yes, Tom Brady gets his numbers, but with a limited number of chances, Oakland wins a rather low scoring affair.
