NFL Power Rankings: 3 Playoff Contenders Holding on for Dear Life

When you are currently in the playoff picture, but so much uncertainty lies ahead, that has a way of making you queasy.

That's how several NFL teams are feeling right now, with inconsistency, injuries and bothersome opponents the main culprits.

So, join in, folks, let's take a look at NFL teams that we can be amused by as they pull their hair out.

It's all in good fun.

3. Dallas Cowboys (6-4)

At 6-4, the Cowboys are on top of the NFC East and have won their last three games, helped by the emergence of rookie running back DeMarco Murray.

So you would think they are just peachy right now.

But that's never the case with a Tony Romo-led team, a team that has consistently disappointed with its inconsistency.

Romo has been spectacular the last three games and there's no question he can be a great quarterback.

But he's shown us too many times that he can flub when the game's on the line, and that will always be in the back of the minds of Cowboys fans.

The Cowboys should beat the Miami Dolphins and Arizona Cardinals next, but what happens when they face the New York Giants?

Stay tuned.

2. Cincinnati Bengals (6-4)

The Bengals deserve a ton of credit this season.

They were widely considered the worst team in the NFL headed into this season, but rookies Andy Dalton and A.J. Green, combined with a surprisingly solid defense have catapulted them into the playoff picture.

But the Bengals still are a developing team, and they've lost two straight games now, albeit to tough competition.

The Bengals have shown they can compete with some top teams in the NFL, but they haven't beat a top team yet, and that spells trouble down the road against the Steelers, Texans and Ravens.

1. Chicago Bears (7-3)

The Bears should be feeling fantastic right now, in prime position for a playoff spot after the team has come together beautifully, rattling off five straight victories.

The only problem is: Quarterback Jay Cutler just broke the thumb on his throwing hand and he could be lost for the season.

Cutler was playing very smart ball before the injury, and now the Bears are left with Caleb Hanie, who has attempted a grand total of 14 passes in his NFL career.

Yikes.
