Jacksonville Jaguars vs. Cleveland Browns (-7)

Although the Cleveland Browns boast a better overall record than the Jacksonville Jaguars, there's no denying that Jacksonville is the hotter of the two teams. The Jags have won two of their past three games, both on the road. 

Meanwhile, Cleveland has lost five of its last six games since losing quarterback Brian Hoyer to a season-ending knee injury. Even worse, the Browns' last two losses have come by 16 and 21 points, respectively.

So although the records don't suggest it, these are two teams trending in opposite directions heading into Week 13. The Jaguars are a winning football team in the month of November, and fans should expect them to cover the spread on Sunday.

Arizona Cardinals vs. Philadelphia Eagles (-3.5) 

It's not crazy that the Philadelphia Eagles are favored over the Arizona Cardinals this weekend, but it is surprising that Chip Kelly's squad is favored by more than three points over a 7-4 foe at home, where the Eagles have won just once all year long.

What's more, the Cardinals are streaking, having won four in a row coming into Week 13.

On the field, Arizona has the perfect antidote for Philadelphia's top-ranked rushing attack. The Cardinals possess a fearsome front seven that ranks second in the league in run defense through 12 weeks, allowing just over 81 yards per game on the ground.

And with Carson Palmer and the Cardinals' aerial attack coming on strong in recent weeks, Arizona has all the tools needed to send Philadelphia to 1-5 at home this season.

New York Giants vs. Washington Redskins (-2.5)

The Washington Redskins are in free-fall mode coming into Week 13's prime-time showdown with the New York Giants. 

Not only have the reigning NFC East champions dropped three in a row, but the offense has regressed each week, hitting rock bottom in its most recent outing and scoring just six points in Week 12's embarrassing home loss to the San Francisco 49ers on Monday Night Football.

With Washington on a short week and a much-improved Giants defense coming to town, the Redskins will be in even more trouble this week. Big Blue has won four of five and should be able to find plenty of success against a porous defensive unit that hasn't stopped much of anything in 2013.

The Giants are almost a lock to win this game outright on Sunday. The only question is by how much.
