NFL Football betting odds at WagerWeb Sportsbook and 2007 NFL Regular Season.

Which team will go undefeated for the 2007 NFL regular season?

San Jose, Costa Rica , October, 2007. WagerWeb.com is at the quarter-pole of the NFL season, and four teams remain unbeaten, split evenly among the AFC and NFC; Indianapolis , New England, Dallas and Green Bay are all 4-0.

No team has gone undefeated for a season since the 1972 Dolphins. Players on that team annually break open a case of champagne whenever the final NFL unbeaten falls on a given year.

WagerWeb.com gives you the chance to be on which team you think can make it the distance. Here is a look at the "Final Four";

Indianapolis , the defending Super Bowl champion, is undefeated for the third straight September, has the league's best September record (18-2) since 2002 and has won an NFL-best nine games in a row, including last year's playoffs. Peyton Manning has been his typical All-Pro self, and Joseph Addai has shined in his first season as the featured back. However, the Indy defense took a hit this week as starting linebacker Rob Morris will have season-ending surgery. Indy started last season 9-0 and flirted with the unbeaten mark in 2005 with a 13-0 start. Colts' WagerWeb.com odds: 20-1.

New England is off to its best start since 2004, when it won the Super Bowl for the third time in four years, with an offense energized by the addition of receiver Randy Moss. Moss has seven touchdown catches, most in the NFL., and he's the first player in league history to have 100 yards in receptions in each of his first four games with a new team.

QB Tom Brady leads the league with 13 touchdown passes, his best total in any four-game span in his career. The Pats have outscored their opponents 148-48 and have scored in every one of their 16 quarters.

Incidentally, the Patriots play at two of their fellow unbeatens upcoming: Oct. 14 at Dallas and Nov. 4 at Indianapolis . Pats' WagerWeb.com odds: 15-1.

Dallas is 4-0 for the first time since 1995, the last time the Cowboys won the Super Bowl. The team has scored an NFL-high 151 points, and it seems to be getting better, increasing its margin of victory from 10 to 17 to 24 to 28. QB Tony Romo has become a franchise player, and he and receiver Terrell Owens have formed the best aerial combination west of New England . And the defense, a weak spot in the first two games, has moved up to eighth in the NFL. The Cowboys' Week 6 game against the Patriots very well could be a prelude to a Super Bowl rematch. Cowboys' WagerWeb.com odds: 75-1.

Green Bay is the surprise of the 4-0 bunch, the first time the Pack have done that since 1998. Brett Favre is having his best season in years, and last week he became the NFL's all-time leader in touchdown passes.

Green Bay has won eight straight games dating back to last year, but the team's Achilles' heel is an imbalanced offense. Green Bay throws nearly 70 percent of the time, as the running game has been stagnant, averaging only 54 yards a game on 2.7 yards per attempt. Packers' WagerWeb.com odds: 500-1.

Odds on which NFL team will go unbeaten this regular season;

New England Patriots, 15:1, +$1500; *Risk $100 to win $1500.

Indianapolis Colts, 20:1, +$2000; *Risk $100 to win $2000.

Dallas Cowboys, 75:1, +$7500; *Risk $100 to win $7500.

Green Bay Packers, 500:1, +$50000; *Risk $100 to win $50000.
