Updated Super Bowl odds see Seahawks fall back to the pack

The Seattle Seahawks, New England Patriots, and Green Bay Packers are the co-favorites to win Super Bowl 50 in Santa Clara, Calif., according to updated betting odds available on offshore sportsbook Sportsbook.ag on Monday.

The Seahawks, Patriots, and Packers all come in at 15-2 odds. Both the Patriots and Packers have seen wild fluctuations in their offerings, with New England yo-yoing up and down amidst news of Tom Brady's suspension, while Green Bay took a moderate hit when wide receiver Jordy Nelson was lost for the year.

Seattle, meanwhile, was the lone favorite on Feb. 1 despite losing Super Bowl XLIX to the Patriots, but the Seahawks have since been caught by two teams, with the Indianapolis Colts - which brought in a bevy of offensive talent during the offseason - are just 50 cents behind.

Big movers include the Miami Dolphins and Buffalo Bills, each of which enjoyed fine offseasons, and the Minnesota Vikings. The return of Adrian Peterson alone was enough to cut the Vikings' odds in half, from 60-1 to 30-1.

The San Francisco 49ers took as big a hit this offseason as any team in league history, and that's reflected in their odds, which dropped from 35-1 to 80-1.
