Michigan vs. No. 2 Ohio State preview

Check out the the facts and figures between Michigan and No. 2 Ohio State ahead of their game on Saturday.

David Purdum: The Michigan Wolverines-Ohio State Buckeyes line ticked down toward the underdog Wolverines this week but remains one of the largest spreads ever in the rivalry.

The Buckeyes were consensus 19.5-point favorites over Michigan entering the weekend. Ohio State opened as a 20.5-point earlier in the week.

On Friday, sportsbooks were reporting mixed action on the game. Roughly 65% of the bets and money were on the Buckeyes to cover the spread at ESPN BET. But, at BetMGM, Michigan plus the points was the most-popular college football bet on the board.

Ohio State has twice been favored by more than 20 over Michigan (2014 Ohio State -21; 2008 Ohio State -20.5). The Buckeyes won both games, by 14 and 35 points, respectively.

If the line grows back to 20, Michigan would be the third defending national champion to be a 20-point underdog the following season since 1978, joining the 2011 Auburn Tigers and 2020 LSU Tigers.

The over/under total was sitting at a consensus 42.5 on Friday, the lowest in the series since 2008.

Temperatures are expected to be in low 30s with breezy conditions in Columbus, Ohio.

Tracking the CFP betting action through the season

Doug Greenberg: On Tuesday night, the College Football Playoff selection committee released its latest rankings heading into Rivalry Week, providing both hope and anxiety for bettors who have placed future wagers throughout the season.

Before the season, Alabama was the most-bet team to make the playoff by handle and the third-most-bet by tickets at ESPN BET. The Crimson Tide are currently on the outside looking in at No. 13 in the rankings. On the other hand, third-seeded Miami was the second-most-bet team by money and the fourth-most by bets in the preseason.

The team that gained the most steam throughout the season was undoubtedly Indiana, who is essentially a lock for the playoff at -3500 odds after beginning the season off ESPN BET's oddsboard because it was such a long shot. The sportsbook reports that from the beginning of the season until the first CFP rankings released on Nov. 5, the Hoosiers notched the second-most wagers and fifth-most money to make the playoff.

Bet tracking tool Pikkit notes that Indiana garnered just 42 bets across its entire user base before the season, and has since attracted 20 times that number.

As for who bettors will watch going forward, that honor belongs to South Carolina (+550), which is No. 15 in the CFP rankings and shows the most bets since Nov. 5 at ESPN BET. Pikkit also notes that since Tuesday night, the most popular wager it saw in this market is Ole Miss to miss the CFP (-1200 at ESPN BET).

The Rebels are part of a +6325 parlay at DraftKings that seeks to correctly guess nine of the 12 playoff teams; it is a $5,000 wager to win $321,274.04.

Cowboys lead big underdogs to huge day

Doug Greenberg and David Purdum: Arguably the wildest game of the 2024 NFL season produced the year's largest outright upset when the Dallas Cowboys took down the Washington Commanders on Sunday.

Dallas entered Northwest Stadium as an 11-point underdog after opening at +9.5 at ESPN BET. Washington's spread received support from public bettors to the tune of more than 70% of tickets at multiple sportsbooks, with positive money splits at BetMGM and the fifth-largest handle at DraftKings. ESPN BET also reported a whopping 90% of bets and 87% of handle on the Commanders moneyline, while BetMGM said Dallas (+450) was the third-most-bet underdog to win of the day.

Washington never truly got close to covering, with its largest lead being six points in the third quarter. Throughout the contest, bettors took advantage of the Commanders' apparent struggles and backed the Cowboys at a 66% clip on the live moneyline at ESPN BET.

The end of the game got unhinged when the two teams rattled off 41 combined points -- the most in the final nine minutes of regulation since 2012, per ESPN Research -- after scoring just 19 combined points up to that point, an incredible result for bettors who took the over, which closed around 45.

"The over in the Cowboys-Commanders game was the best result of the morning for the customers, although it took a while to get across the line," Craig Mucklow, vice president of trading for Caesars Sportsbook, said in an email to ESPN, noting that it was the second-biggest decision of the day for the book. "The crazy ending delivered for the over bettors."

The Cowboys are the first double-digit underdog to win outright this season, the latest in the season for that to occur since 2016, according to ESPN Research. Dallas and the Carolina Panthers also became the first two teams to cover as double-digit underdogs this season, breaking a five-game ATS winning streak for big favorites.

Other dogs barking

Sportsbooks have been limiting the number of big favorites in general this season, anointing just seven double-digit faves thus far, the fewest through Week 12 since 2016. They could be onto something.

Aside from the Cowboys, the Tennessee Titans also won outright as big underdogs, 32-27 against the Houston Texans, who closed as 7.5-point favorites. Dallas and Tennessee are the 11th and 12th teams to win outright as at least seven-point underdogs, tying the most wins for such teams through Week 12 in the last 20 seasons, per ESPN Research.

For the Titans, it ends an ugly ATS skid that saw them fail to cover in six straight and go a league-worst 1-9 against the number entering Sunday.

Meanwhile, Sunday's other double-digit underdog, Carolina, nearly pulled off a monumental win against the Kansas City Chiefs after closing at +10.5. The Panthers have covered in three straight contests for the first time since 2022.

It was another narrow victory for the reigning back-to-back Super Bowl champion Chiefs, who are 10-1 straight up but 4-7 ATS on the season, tied for the third-worst spread record in the NFL. Kansas City has failed to cover in five straight, tied for its longest ATS losing streak under head coach Andy Reid.

Odds and Ends

• A bettor at Caesars Palace in Las Vegas placed a $1 million bet on the Los Angeles Rams +3 (-120) in their Sunday primetime game against the Philadelphia Eagles, the sportsbook reported on social media.

• The San Francisco 49ers closed as 6.5-point underdogs to the Green Bay Packers, snapping the 49ers' streak of 36 regular-season games being the favorite. It was the third-longest such streak in the Super Bowl era. The 49ers hadn't been an underdog since the 2022 NFC Championship Game against the Los Angeles Rams.

• Tampa Bay Buccaneers running back Bucky Irving was all the rage in DraftKings' prop market this week. More money was riding on Over 14.5 yards for Irving's longest run than any other player prop on the board at DraftKings. It was a winning wager thanks to a 56-yard scamper in the Bucs' rout of the Giants. At the same time, Irving was the most popular bet at DraftKings not to score a touchdown at -200 odds, a losing wager due to Irving's 6-yard touchdown run.

• It's no wonder the Lions are the betting public's darling this season. The Lions improved to 9-2 against the spread this season with Sunday's 24-6 win. They were the most bet team Sunday at multiple sportsbooks. Coach Dan Campbell improved to 47-26 against the spread in his career over the Indianapolis Colts. That's the best record against the spread of any coach with at least 10 games in the Super Bowl era. Detroit is 44-18 under Campbell, who took over in 2021. That's the best ATS mark of any team in the league during that span.

• Bookmakers are noticing a trend this season -- favorites are rolling in the afternoon, much to the delight of the betting public. "The morning games were close to breaking even; the book's saving grace was the upsets in Houston and Washington," Mucklow of Caesars Sportsbook said. "As seems to be the case each week, the afternoon games continue to belong to the customers, with favorites going 34-11 for the season straight up."
