• BetMGM is projecting betting handle on the Super Bowl to be eclipse $10 million at its sportsbook.

• The mayors of Tampa and Kansas City have placed their bet against one another. If the Chiefs win, Tampa mayor Jane Castor will send a Gates BBQ meal to healthcare workers in the Kansas City region. If the Buccaneers win, Kansas City Mayor Quinton Lucas will send food to local Tampa healthcare workers from a restaurant of Castor's choice.

'The Super Bowl can be a great escape from thinking about so many other things going on in the world, and Mayor Castor and I look forward to an exciting game Sunday where Mahomes will once again show the world he's the greatest player in the league.

Super Bowl 55 Ratings

Super Bowl Week

• For the most part, the Super Bowl point spread has not budged off Kansas -3 (-120) as of Wednesday - despite lopsided action on the favored Chiefs. At sportsbook PointsBet, 92% of the point-spread money that had been wagered was on Kansas City.

The action at FanDuel was running around 80% on the Chiefs, but sportsbook director John Sheeran said he has no intention of moving the line off of the key number of three.

'We're definitely not going to move the number just to get money on the other side,' Sheeran told ESPN on Tuesday. 'We disagree with that as a bookmaking strategy. We believe the right number is three, and we'll live with that from here to kickoff.'

• William Hill U.S. reported taking two interesting prop bets this week:

$3,000 on Patrick Mahomes to throw zero touchdowns at 15-1. The bet, which was placed in New Jersey, would pay a net $45,000.

$1,000 on Tom Brady to throw six or more touchdowns at 40-1. The bet, which was placed in Nevada, would pay a net $40,000.

• The over/under on Chiefs receiver Tyreek Hill's receiving yards has grown from 86.5 to 92.5 at FanDuel, and money continues to pour in on the over. 'At 92.5 [yards], we've taken $23,265,' Sheeran told ESPN on Tuesday. 'Of that $23,265, $23,101 is all on the over.'

• As of Tuesday, 'orange' was attracting the most action with 31.1% of the money in BetMGM's odds on what color of Gatorade will be dumped on the winning coach. 'Red/pink' is next with 18.8% of the money, followed by 'yellow/green/lime' at 16.6%.

• Interesting strategy: A bettor with FanDuel in New Jersey placed bets on the exact score of the Super Bowl: 1) $500 on Bucs 34, Chiefs 17 at 130-1, and 2) $500 on Chiefs 34, Bucs 17 at 170-1.

• Nevada Gaming Control began tracing the betting on the Super Bowl in 1991. Since then, the state's sportsbooks have suffered a net loss on the Super Bowl only twice: 1995 Chargers-49ers and 2008 Giants-Patriots.

• It's known as the bookmaker's dream: The favorite wins the game, eliminating all the money-line bets on the underdog, but doesn't cover the spread for the betting public, which almost always gravitates to the chalk. It has happened five times in Super Bowls, most recently in 2009 when the favored Pittsburgh Steelers (-7) defeated the Arizona Cardinals 27-23.

Bookmakers expect to be rooting for it again. 'That's always the Super Bowl dream,' Murray of the SuperBook said.

• Johnny Avello, sportsbook director for DraftKings, said his shop was facing a $1 million liability on the Buccaneers in his odds to win the Super Bowl.

• The largest bets on the Super Bowl are normally in the million-dollar range and are typically placed by casino VIPs, not professional sports bettors. Bookmakers do not make a habit of taking their largest bets from their sharpest customers.

• The tradition of dumping Gatorade on the Super Bowl-winning coach dates back 35 years, and people love to bet on it. Orange has been the most common color, used 33% of the time since Super Bowl XL, including with the Chiefs last year.

• Super Bowl favorites are 35-19 straight up and 27-25-2 against the spread.

• There have been 26 overs, 26 unders and one push in the Super Bowl (no over/under on Super Bowl I).

• The coin flip has landed on tails 29 times and heads 25 times.

• The largest bet on the Super Bowl coin flip as of Monday morning at FanDuel was $5,000 on heads (-103).

• There's big believer in Chiefs receiver Sammy Watkins in New Jersey. Last week, a bettor with William Hill in New Jersey placed three bets on Watkins, totaling $11,666 with a chance to win $399,990.

1) $6,666 on Watkins to score the first touchdown for Kansas City at 15-1. The bet would pay a net $99,990.

2) $4,000 on Watkins to score first touchdown of the game at 25-1. The bet would pay a net $100,000.

3) $1,000 on Watkins to be named Super Bowl MVP at 200-1. The bet would pay a net $200,000.

The early action

• There was a slight difference of opinion on the opening line at sportsbooks. The consensus opening number was Kansas City -3, but several sportsbooks, including the SuperBook at Westgate Las Vegas, went a little higher, opening at Chiefs -3.5.

'Three weeks in a row now, where we opened up one of these Buccaneers games, the sharp guys just flooded us with Buccaneers bets,' said John Murray, executive director of the SuperBook.

By the Monday after the matchup was set, the line had settled at Kansas City -3, with added vig to bet the favored Chiefs.

• In the first 24 hours at DraftKings, 77% of the point-spread bets and 78% of the money bet on the point spread was on the Chiefs.

• The over/under, which opened as high as 57.5, had been trimmed down to 56.5 on early action.

The key number: 3

• Three is the most common margin of victory and hence considered the most key number when betting on the NFL. Including the playoffs, 14.3% of games this season had a margin of victory of three. Three was the most common margin of victory in the 2020-21 season.

• Forty-one games had closing lines of -3 this season, including the playoffs. Teams favored by three went 25-16 straight-up and 20-21 against the spread this season.

• According to ESPN Stats & Information's database, 1,569 games have featured a point spread of -3 in the Super Bowl era. The winning percentage for the favorites in those games: 58.4%. The favorites' winning percentage against the spread in those games: 48.9%.

• Seven Super Bowls have had a closing point spread of -3. The favorites in those games are 4-3 straight-up and against the spread.

• Five Super Bowls have been decided by exactly three points.

• 'I can't imagine it going to 2.5,' Murray of the SuperBook said. 'I could be wrong about that, but seems crazy to me. Kansas City was considered the best team in the league the whole way. I can't believe it would go under 3. To go to back to 3.5, it would just take bets from the right people, the most respected people. And they could move it right back up, if certain groups that we really respect came in and laid 3, we would say, 'OK, let's go back to 3.5, because that's what we thought it should be to begin with.'

Mattress Mack is putting plenty of springs in the game.

The Houston furniture store owner named Jim McIngvale made a major wager on Wednesday. Via David Purdum of ESPN.com, McIngvale flew to Colorado, logged into the DraftKings mobile betting app, and placed a $3.46 million bet on Super Bowl LV.

Super Bowl 2021 Bet Payout

Mattress Mack took the Buccaneers getting 3.5 points. The magnitude of the bet triggered a higher vigorish (-127, more than the usual -110). He’ll win $2.72 million if the bet pays off.

The bet helps Mattress Mack hedge against his store’s risks arising from sports-based promotions. Customers who spend $3,000 or more on a new mattress get their money back if the Buccaneers beat the Chiefs on Sunday.

Mattress Mack, given the point spread, could have it both ways, if the Chiefs win by fewer than four points. He’d keep his mattress money, and he’d carry away another $2.72 million from DraftKings.

Via Purdum, the largest Super Bowl bet happened 19 years ago, when someone placed a $4.8 million money-line wager on the Rams to beat the Patriots with MGM in Las Vegas.
