Sure, it's only two weeks into the NFL season. Still, look who is undefeated — and who is winless.

Yep, that's the Bears and Buccaneers and Chiefs and Texans at the top of the standings. And the defending division champion Vikings and Cowboys at the bottom.
Chicago, Tampa Bay, Kansas City, Miami and Pittsburgh all missed the playoffs last season. They all are 2-0 after Sunday's games.

Brett Favre had his worst game for the Vikings, throwing three interceptions and losing a fumble as the Miami Dolphins held out Adrian Peterson on fourth-and-goal to preserve a 14-10 victory over Minnesota on Sunday.

Koa Misi recovered Favre's fumble in the end zone for a touchdown and Brian Hartline scored on a 5-yard pass from Chad Henne to keep the Dolphins (2-0) undefeated.

The 40-year-old Favre was 19 of 28 for 197 yards. He threw two interceptions at home all of last season but topped that total in the home opener.

Peterson rushed for 145 yards and a touchdown for the Vikings (0-2), who forced two fumbles in a mistake-filled game.

Not getting wins are highly touted Minnesota and Dallas. It's too early to panic but the Vikings have the deeper hole because Chicago and Green Bay already are two games in front of them in the NFC North.

“It's a 14-game season now and we're sitting at the bottom of it,” said Favre, who was 22 of 36 for 225 yards and had a dreadful 44.3 rating after throwing three interceptions and losing a fumble for a touchdown in a 14-10 home loss to the Dolphins.

“What we do with it from here remains to be seen. It won't be any easier.”

The Bears won seven games in 2009, four more than the Buccaneers managed. Yet Tampa Bay leads the NFC South after a 20-7 win at Carolina.

“It feels good to win,” said second-year quarterback Josh Freeman, who has Tampa Bay off to its best start since it began 4-0 in 2005. “It feels good to win in a team effort. The offense came out and got some points on the board. The defense played lights-out in the second half. They held them out of the end zone and shut them out. It felt great to go out and play a divisional opponent and get the win.”
