Kansas City Chiefs Fatigue? We totally get it with Patrick Mahomes, Travis Kelce and Co., set to play in their fifth Super Bowl in the last six years. That’s unprecedented — but so are some of the eye-popping viewership and sports betting projections for Super Bowl 59, set for a 6:30 p.m., ET kickoff Feb. 9 in New Orleans (FOX). In fact, respected analyst Eric Ramsey of partner site Legal Sports Report has projected this year’s Super Bowl betting handle will eclipse $1.5 billion across regulated U.S. markets. Chiefs’ dynasty showing no signs of slowing down ... The AFC-champion Chiefs, as you have no doubt heard, are a win away from completing the first championship three-peat in the Super Bowl Era. That historical title run would be bookended with victories over the Philadelphia Eagles after Kansas City outdueled Philly 38-35 two years ago in Super Bowl 57 in Arizona. Mahomes already has a pair of Super Bowl wins over the San Francisco 49ers. And at age 29, the K.C. QB is already threatening Tom Brady’s GOAT status as he pursues his fourth Big Game victory/MVP award and his 18th playoff win overall — against only three losses. Since taking over as the Chiefs’ full-time starter in 2018, Mahomes has known nothing but success. He’s won nearly 80 percent of his regular-season starts (89-23) and has advanced to at least the AFC Championship Game in all seven seasons. Under Reid, Kansas City has won nine straight AFC West titles overall, and enters Super Bowl 59 having won an amazing 17 straight one-score games after outlasting the Buffalo Bills (again) 32-29 in in the AFC title game. But Chiefs Fatigue is growing with each K.C. win  With every Kansas City gridiron triumph, though, Chiefs Fatigue grows stronger. And just when NFL Nation was breathing a sigh of relief with the end of the Brady/Bill Belichick New England Patriots’ run of six Lombardi Trophies in nine Super Bowl appearances, Mahomes and the Chiefs took their place on the podium the very next season in 2019. The seemingly-on-repeat Reid and Mahomes TV commercials and the made-for-TV Kelce-Taylor Swift storybook romance have followed in the ensuing years. And now the franchise is on the precipice of adding three-peat to its burgeoning trophy case. But beyond the boundaries of Chiefs Kingdom, most of America has had enough.  K.C./referee conspiracies have risen to an all-time high with social media posts accompanying every semi-marginal call in Chiefs games.  And many NFL fans and casual Super Bowl-only viewers who were openly rooting for a Bills breakthrough in the AFC title game are now proclaiming they’ll find something else to occupy their time on Feb. 9. But the funny thing about sports dynasties is they tend to have the opposite effect on event interest and audience.  One sure bet is that the growing legions of both Chiefs Haters and Bandwagon Chiefs fans will be tuning in one way or another on Super Bowl Sunday while backing their rooting interests with wagers (see below). And as for the NFL-is-rigged conspiracy theorists, how does it make any sense that small-market Kansas City is the Chosen Franchise when the likes of Uber-popular or major-market teams such as the Dallas Cowboys, Chicago Bears or New York Jets haven’t danced beneath a Super confetti shower in three decades or longer? Record-setting figures on tap for Super Bowl 59 viewership, betting handle? Last February’s Chiefs-49ers Super Bowl drew a record 123.4 million average viewers across all platforms. And despite some NFL viewership declines this season, there is hope that Super Bowl LIX will top those numbers after Chiefs-Bills averaged 57.7 million average viewers to emerge as the most-watched AFC Championship Game since 1988.  Only the 2009 Minnesota Vikings-New Orleans Saints NFC title game (57.9) drew a larger non-Super Bowl NFL game audience. Meanwhile, Ramsey reports that a nearly 225 million Americans across 40 states and territories now have access to legal sports betting. And that helps lead the LSR model to project a record Super Bowl 59 handle of $1.5 billion-plus, topping the current record of nearly $1.3B a year ago. Super Bowl betting has increased every year since outside-of-Nevada U.S. sports wagering became legal in 2018.   Ramsey says the exploding popularity of secondary markets — such as prop betting and same game parlays —  are helping drive the record Big Game wagering figures. Prop wagering, like these Super Bowl 59 QB props posted for Patrick Mahomes and Jalen Hurts, is actually now accounting for a bigger percentage of the Super Bowl handle than bets on the traditional point spread, moneyline and total. And, circling back to our main point here, the Super Bowl 59 matchup doesn’t exactly hurt, either. “The Chiefs and the Eagles happen to be two of the most polarizing teams in the country, with rosters full of the league’s most popular players — Patrick Mahomes, Travis Kelce, and Saquon Barkley among them,” Ramsey writes. “The addition of Taylor Swift to the list of Super Bowl celebrities also increases attention on the Chiefs despite their home state of Missouri remaining on the short list of states without legal sports betting.” The Chiefs opened as a 1.5-point favorites over Eagles with a game total of 48.5 points.
