Another week, another unbeaten foe for Patriots

Posted by ESPN.com's Tim Graham

Here's an interesting fact:

For the fifth straight week, the New England Patriots will try to hand an opponent its first loss.

Sure, everybody started the season 0-0, but there's a certain degree of difficulty strategizing for an opponent with no blueprints for victory. The Patriots will have to be the first ones to figure it out again.

The Patriots will visit the 4-0 Denver Broncos on Sunday.

The Patriots have defeated the 0-0 Buffalo Bills on opening night, lost to the 1-0 New York Jets in Week 2, beat the 2-0 Atlanta Falcons in Week 3 and held off the 3-0 Baltimore Ravens on Sunday.

"You know, we haven’t really watched a tape of a team that’s lost a game yet," Patriots coach Bill Belichick told reporters at his Monday news conference. "You can say 'Well, this is how so-and-so beat them in the regular season.' We haven’t been able to say that yet."

Belichick will try to be the first to knock off a team that in the preseason looked easily knockoffable but is atop the AFC West. Belichick's former offensive coordinator, Josh McDaniels, seemingly has survived the initial turmoil of the Jay Cutler ordeal and Brandon Marshall mess.

"I know they’ll be well-prepared," Belichick said of McDaniels and Broncos defensive coordinator Mike Nolan. "I know they're going to work hard. They'll look at everything and try to get every tendency, tip and advantage on us, and we'll have to try to do the same thing.

"In the end, it will be how the players play next Sunday. Hopefully, we’ll be ready to go next Sunday. We’ll need to be."
