NFL Picks Week 4: Which Teams Will Stay Undefeated or Winless?

Through three weeks, the NFL has just three undefeated teams and five others that are winless. The rest of the 24 teams have at least one win and loss. 

Here's a look at the remaining eight and how they might fare this weekend:

HIGHLIGHT GAME: Detroit Lions (3-0) at Dallas Cowboys (2-1)

Last Sunday was a big test for the Lions, as they hadn't beat the Vikings in the Metrodome since 1997, and winning the game meant being 3-0 for the first time since 1980. But this weekend might be the first real test for Detroit. The combined records of the teams they've beaten is just 2-6, and the Cowboys are likely the most complete team on the schedule to date.

Playing them in Dallas won't be easy, especially with the expected media hype that will surround the game. However, this game comes down to how well the Lions can keep Anthony Spencer and DeMarcus Ware out of the backfield. Detroit's offense sputtered when the Vikings created pressure in the first half Sunday. They'll lose if that happens against the Cowboys this weekend. 

Prediction: Cowboys 24, Lions 21 

Denver Broncos (1-2) at Green Bay Packers (3-0)

Elvis Dumervil and Champ Bailey look like they could play, and I think that defense could give the Packers some problems. But how can you pick against the undefeated, reigning champions at home? 

Packers 28, Broncos 13

Buffalo Bills (3-0) at Cincinnati Bengals (1-2)

Is there going to be a hangover effect for the Bills after knocking off the Pats? Can they handle the expectations of fans thinking they should win most weeks? Getting to 4-0 is tougher than you might think.

Bengals 21, Bills 20

Minnesota Vikings (0-3) at Kansas City Chiefs (0-3)

The mindset of these two teams can't be good. The Vikes have blown double-digit leads in each of their three losses, and it took the Chiefs until Week 3 to realize a season was being played. I'll take Adrian Peterson and Minnesota's defense on the road.

Vikings 31, Chiefs 20 

Washington Redskins (2-1) at St. Louis Rams (0-3)

Can the Rams figure this season out before it's too late? I'm not sure it happens this week, as the Redskins have a defense that will give Sam Bradford problems. 

Redskins 20, Rams 16

Miami Dolphins (0-3) at San Diego Chargers (2-1)

The Chargers always seem to play down to their competition, as evidenced last week against the Chiefs. The Dolphins have to make a long trip out West, which hurts their chances of getting into the win column.

Chargers 31, Dolphins 27 

Indianapolis Colts (0-3) at Tampa Bay Buccaneers (2-1)

The Colts gave us a good game in prime time on Sunday, but this Monday nighter looks like a snooze-fest. Josh Freeman and the Bucs offense jumps on the Colts defense, and Curtis Painter can't complete a Manning-like comeback in Tampa Bay. 

Bucs 32, Colts 20
