NFL free agency: Bears' Super Bowl odds fall after Andy Dalton signing

Early NFL free-agency signings triggered adjustments to the odds to win the Super Bowl at sportsbooks around the nation. Some moves were seen as positive, and others, well, not so much.

The possibility of landing a marquee quarterback this offseason had caused the Chicago Bears' Super Bowl odds to improve slightly in recent weeks. But on Tuesday, after the reported signing of veteran quarterback Andy Dalton, Caesars Sportsbook by William Hill dropped the Bears' odds from 40-1 back to 50-1.

The Bears were considered a possible landing spot for Seattle Seahawks quarterback Russell Wilson, if he were to be traded. But ESPN's Adam Schefter reported Tuesday that Seattle told the Bears that Wilson would not be movedat this time.

"The Bears' market trended a bit downward on the off chance they landed a trade for [DeShaun] Watson or Wilson," a William Hill representative told ESPN. "With the Dalton signing likely ruling that out, their price went back up."

The New England Patriots have made the biggest splash in free agency so far, signing a bevy of players, including tight end Hunter Henry and wide receiver Nelson Agholor. The Patriots' Super Bowl odds improved from 40-1 to 35-1 this week at Caesars Sportsbook by William Hill.

The Kansas City Chiefs remains the consensus Super Bowl favorites, listed at +525 at Caesars Sportsbook by William Hill, followed by the defending champion Tampa Bay Buccaneers at +900.

BetMGM's sportsbook reported taking a $25,000 bet on the Buccaneers to win the Super Bowl last week that would pay a net $200,000.
