With two weeks of the NFL season in the books, several teams have seen their odds of winning the Super Bowl altered dramatically. A fast start for a handful of teams has improved their forecast, while others who have opened poorly are now longer odds to win it all.
Here are six teams whose title odds have changed the most (odds courtesy Las Vegas' LVH Superbook):
Moving up the board
Miami Dolphins (Week 1: 40-1; Week 2: 30-1; Week 3: 20-1)
Miami has opened the season with back-to-back road victories over Cleveland and Indianapolis, thanks in large part to the exploits of second-year quarterback Ryan Tannehill. The Texas A&M product has thrown for 591 yards and a pair of touchdowns while completing better than 65 percent of his attempts. With Brian Hartline and Charles Clay joining Mike Wallace as part of a versatile vertical attack, expect the Dolphins' improved offense to get even better.
The Dolphins are early one-point favorites for Sunday's home opener against the Atlanta Falcons.
Kansas City Chiefs (Week 1: 50-1; Week 2: 40-1; Week 3: 25-1)
Hail indeed! The Chiefs are easily the most surprising success story after two weeks, already matching their win total from all of last season. Opening against the sad-sack Jacksonville Jaguars certainly helps - but Kansas City built off the momentum of that 28-2 drubbing to stifle the Dallas Cowboys en route to a 17-16 triumph. Stout defense has been the biggest factor, with the Chiefs entering Monday second in the NFL in fewest rushing yards allowed per game (54).
Kansas City is listed as a three-point underdog for its Thursday night showdown in Philadelphia.
Oakland Raiders (Week 1: 500-1; Week 2: 300-1; Week 3: 200-1)
The Raiders aren't suddenly Super Bowl contenders - their odds are still among the worst in the league - but back-to-back strong games have provided hope for a respectable season. Like the Chiefs, Oakland benefited from playing the Jaguars in Week 2, but looked just as strong in a narrow loss to Indianapolis the week before. Running back Darren McFadden and QB Terrelle Pryor key a rush attack averaging a league-best 198.5 yards per game.
Oakland has a major challenge Monday night, sitting as 14.5-point underdogs against Peyton Manning and the host Denver Broncos.
Moving down the board
Minnesota Vikings (Week 1: 60-1; Week 2: 100-1; Week 3: 200-1)
A year ago, Adrian Peterson's near-record rushing performance and a passable defense was enough to carry the Vikings into the post-season. Through two games in 2013, Peterson is holding up his end of the bargain - but the defense isn't close to doing the same. The Vikings have surrendered 65 points in consecutive losses to Detroit and Chicago, getting gashed both on the ground (26th in yards allowed per game) and through the air (25th).
The Vikings are presently five-point favorites for Sunday's tilt with the visiting Cleveland Browns.
Dallas Cowboys (Week 1: 20-1; Week 2: 25-1; Week 3: 40-1)
It wouldn't be an NFL season without turmoil in the Lone Star State. The Cowboys did just enough to escape with a Week 1 win over the New York Giants, then laid an egg against the team with the worst record in the league a season ago. Tony Romo has been just ordinary at quarterback, but that hasn't been the issue; the Cowboys can't run the ball (27th in yards per game) and are having problems against opposing QBs (24th in passing yards allowed per game).
Dallas has been installed as a four-point favorite for Sunday's showdown with the visiting St. Louis Rams.
Washington Redskins (Week 1: 30-1; Week 2: 40-1; Week 3: 50-1)
As Robert Griffin III goes, so go the Redskins' title chances - and aside from some garbage time in a Week 2 loss to Green Bay, RGIII has been stuck in neutral. He has already thrown five interceptions - just two fewer than he had all of last season - and has only nine carries for 25 yards after piling up 815 rushing yards in his rookie season. The Washington defense has also been to blame, surrendering 71 points in losses to the Eagles and Packers.
Washington is listed as a one-point favorite for Sunday's home game against the Detroit Lions.
