Odds are that Tom Brady will return to the New England Patriots, according to American sportsbooks.

The Tennessee Titans, Las Vegas Raiders, Los Angeles Chargers and San Francisco 49ers are among the next tier of contenders on oddsboards in New Hampshire, New Jersey and Nevada.

"We're getting bets on all these teams," Jeff Sherman, vice president of risk management at the Westgate SuperBook in Las Vegas, said. "We even have a few wagers on the Vikings at 1,000-1."

The SuperBook in Las Vegas also received recent interest on the 49ers and shortened their odds from a 100-1 to 12-1.
