NFL Week 7 Picks: Tony Romo's Dallas Cowboys and Favorites on Upset Alert

Oh, how the mighty have fallen in 2011.

No, not the U.S. economy (seriously, it's bad), but NFL powerhouses.

Teams like the Philadelphia Eagles, Indianapolis Colts, New York Jets and Dallas Cowboys are among the franchises who had high preseason expectations, but who are off to a slow start.

Vince Young's "Dream Team" sits at 2-4 as we head into Week 7, while Rex Ryan's cocky ball club needed a Monday night win over the winless Miami Dolphins just to get to .500 on the year.

While these teams remain favorites, week after week, here are three favorites on upset alert in Week 7: 

Dallas Cowboys

The 2-3 Cowboys are 13-point favorites at home against the winless St. Louis Rams on Sunday.

If that doesn't sound like a trap game, then Tony Romo will win a Super Bowl before he retires.

Although a photo of the Rams offense appears in the dictionary under the word "mediocre," this is a Cowboys team who blew a 24-point second-half lead when they last played at Jerry's World. 

Oakland Raiders

How much longer can the Raiders rally behind the death of beloved owner Al Davis?

The answer is as long as Carson Palmer, or Kyle Boller, allow.

Sunday's matchup with the Chiefs will be tougher than it looks on paper, with Kansas City coming off a bye and filled with confidence after having won two games in a row.

If the quarterback transition gets bumpy this weekend, look out Raider nation. 

Detroit Lions

No one thought the Falcons would be in position to upset anyone this season after finishing 13-3 in 2010, but here they are.

The Detroit Lions have huge running back concerns and are in danger of dropping their second game in a row in their own building.

Megatron must be on his game, as must Matthew Stafford, if the Lions are to fend off the hungry Falcons.
