Bears' forecast suddenly cloudy

"You just want to focus on the details and when your number is called, just respond."

Hayden, who had two pass breakups Sunday, has 53 career starts, including one in which he ran back a Rex Grossman pass for a pick-six on football's biggest stage.

He has something else too. Fresh legs.

So does Eric Weems, who was returning kicks and punts in Hester's place. And so does Michael Bush, who took over for Forte.

Bush averaged 2.9 yards per carry, but he was the most valuable running back on the field. He scored on a pair of 1-yard touchdown runs, and ran for four first downs, including one on fourth-and-1.

"That's what we brought Michael here for," Smith said.

If the Bears are going to keep this one-game roll going, they are going to need more heroes and new heroes. It's the nature of the NFL.

Against the Vikings, the Bears received contributions that some might say were unexpected from wide receiver Earl Bennett and tight end Matt Spaeth.

"You get to this point in the season, you are going to need more guys stepping up like that," Smith said.

The true test of a football team isn't how well it can play when every planet is aligned in its universe. It's how well it can play when comets come crashing into their plans.

Those comets are flying now.
