The Chicago Bears and Cleveland Browns have been bet on most to win the Super Bowl, according to Las Vegas sportsbooks.

"It's been kind of overwhelming, the support [for the Bears]," said Alan Berg, the senior oddsmaker for Caesars Sportsbook. "Every time the Bears go to the playoffs, the following year, the money just pours in. Everybody gets optimistic."

The Bears are 9-1 to win the Super Bowl at Caesars, the fourth-best odds behind the New England Patriots and Kansas City Chiefs, who are co-favorites at 7-1, and the New Orleans Saints at 17-2. The Browns are 10-1.
