Covering the Tracks: Purdue-Minnesota

A look at Saturday’s Purdue-Minnesota game from a gambling perspective.

Recap

Worst day for the column, maybe ever.  Just an evisceration.  On paper, Purdue was more efficient overall than Illinois, but turnovers are the great equalizer and if you lose that, it is hard to overcome.  Nitro Tuggle was a couple of yards short of hitting his over, which, if you watched, seemed like it should have hit on more than a couple of occasions.  Tuggle getting tackled at the one certainly hurt the ATD crowd as well.  Onward.

Executive Summary

Purdue heads to Minneapolis needing a win after playing a great game on paper last week in a double-digit loss to Illinois.  The Purdue offense showed plenty of spark, but turnovers combined with defensive blown coverages proved to be too much for Purdue to overcome.  Purdue has won its last two against Minnesota, and Minnesota is coming off a big loss against Ohio State.  Neither team is in a great spot.  There is no big lean on spread or total, but early on most of the money has come on Purdue moving the spread down to 7.5 from 9.5 and fluctuating around 8.5.  The total has come down, with the cause most likely being the chance of wind Saturday night.  The total and spread are both right around key football numbers with 49.5 and 7.5, respectively, so any bets may want to factor in reducing the odds on a bet by taking a point.

Miscellaneous Factors

· Familiar Faces.  Purdue fans will recognize three names on Saturday when the Boilers face off against Drew Biber, Jaden Ball, and West Lafayette’s own, Mo Omonode (although Omonode is injured).  Biber had a limited role in his four seasons (1 redshirt year) with Purdue catching just 15 passes and scoring 1 touchdown.  He has 8 catches so far this year with 4 of those coming in the win against Rutgers two weeks ago.  Jaden Ball is a backup offensive lineman.  

· TWindy City. While not a massive cause for concern, the weather forecasts do predict a little bit of wind in Minneapolis on Saturday night.  Estimates show wind speeds around 13 mph, which could help the under betters a little bit.

· Coaching Competency.  One clear consideration for Boiler backers this year as opposed to last year is the very obvious coaching competency that exists along the Purdue sideline.  From a scheme standpoint, the Boilers are significantly improved and the advanced analytics back this up.  Purdue was the more efficient team on Saturday, but still lost to Illinois in part due to turnover, dropped passes, and a couple defensive blown coverages.  The difference between a good team and a bad team often can be found in the turnover margin.  This poses an interesting spot for Purdue the rest of the season.  Can Purdue stay out of its own way when it comes to covering spreads?  The coaching staff will have Purdue in a position to be competitive in games like this, but is the talent level high enough to execute?

Gambling Analysis

Numbers: I want to caveat the numbers, immediately: so far, there has not been much money wagered on this game.  Purdue’s past three games have all featured ranked teams (ND, Illinois) or teams with a significant national brand (ND, USC) so the amount bet on Purdue games has actually been pretty high.  This is the first week in a while where that is not the case.  With that being said, almost immediately the number jumped from Gophers -9.5 to 7.5.  Money so far has been heavy on the Boilers to cover the 7.5.  The total also opened up higher but has since decreased to 49.5.  The hooks are interesting for both spread and total given the football numbers they surround.  If you like Minnesota, the juice sacrifice is probably worth it to get under 7.  The same goes for over bettors with getting under 49.  This column has always tried to take Purdue games with low gambling amounts with a grain of salt, however, the amount showing on Purdue early is certainly interesting and makes us lean Minnesota.  There is not much regarding the total as we are almost even on bet %, so there is a slight, and I mean slight, contrarian angle on the over.  EDGE: Minnesota Spread, Over

Trends: Odom’s teams have been very good as away underdogs.  The UNLV teams covered at a very high percentage in these spots, however, Purdue is 0-1 ATS in this position after failing to cover at Notre Dame.  There is no clear edge on Odom total trends, as his teams have put up points after a loss but typically have not as an away underdog.  However, the over hit easily (thanks to ND) in the game at Notre Dame this season.  Fleck’s Minnesota teams are basically .500 in all three applicable spots.  There is not a large deviation one way or the other, but when you have been coaching at one place for 8 years, that should be the case.  Minnesota has shown a slight propensity to cover after a loss, showing that Fleck can typically rally his troops.  The over in Minnesota games has struggled a little bit when Minnesota has equal rest and is a home favorite, however, the over has seen a lot of success after a Minnesota loss.  EDGE: Slight lean to Purdue, slight lean to over.

Situation: Both teams come into this game really needing a win.  Barry Odom has not lost four straight games since 2019 with Missouri.  If Purdue wants a chance to go bowling, this is essentially a must win game.  Purdue showed some flashes in Illinois, but the defense really struggled, and the public perception probably reflects as such.  Minnesota is coming fresh off a beatdown at the hands of Ohio State.  The Minnesota offense put up three points while the defense allowed the Jeremiah Smith Heisman Campaign to really take off en route to giving up 42 points.  Neither side can feel too good about their team, but Minnesota does have a Big Ten win beating Rutgers.  The spread was a bit concerning to me when it opened, and my gut said “9.5?!? Purdue can cover that” which really makes me concerned that Minnesota is the side.  Both defenses really need a bounce back and a windy night in Minneapolis could help that.    EDGE: Push, Under.

Total Analysis:  I will be honest, I have virtually no feel here.  There is no real key indicator here for either spread or total.  Ultimately, I still think Purdue is too far away defensively to win this game, and the Purdue offense has been able to show signs of life, although the struggles of the receivers last week were a major red flag, so I lean Minnesota and the over.  I think the Sportsbooks have these numbers pretty dead on, so I will be buying the hooks.  If the wind picks up, and each team struggles to throw the ball, it could mean an easy under.  At the very least, I have a nice emotional hedge if the Boilers decide to go win what should be a winnable game.  Minnesota 28, Purdue 21

Welcome to the 2025 edition of Covering the Tracks.  This column is a weekly preview of the upcoming Purdue game through the lens of gambling metrics.  The age-old saying is that Vegas always wins, so building upon that, we have decided to break down the game using pieces of information that Vegas and sportsbooks so graciously provide us.  Whether you choose to dabble in sports gambling or you’re just an avid Purdue fan who craves any piece of content on the Boilers leading up to game time (or both!), I hope this article can provide some helpful insight to preview the game.   For those unfamiliar with sports gambling terminology, there is a glossary at the end.  I use lines provided by BetMGM sportsbook, but in no way, shape, or form should this be an endorsement of their sportsbook. Disclaimer for those who gamble: ensure you manage your bankroll effectively, bet responsibly, and never bet more than you can afford to lose.   

Glossary:

The spread: Arguably the most used term in all of gambling, the spread refers to the handicapped line set by the sportsbook. For those new to gambling, think of the spread as a prediction by the sports book, given all the circumstances, of what the difference between the two teams is. The favorite will be listed with a negative spread, while the underdog will have a positive spread. The spread is put in place as a handicap to make the underdog and favorite more equal. For example, if Purdue is -4.5 against an opponent, a sportsbook would expect Purdue to win by 4.5 points.  It is worth noting that the sportsbooks are in the money-making business.  So a spread may not necessarily be an accurate depiction of what the sportsbooks think will happen, but rather, at what spread number can the sportsbook generate action on one side while comfortably limiting their exposure to a big loss.

Odds and How to Read Them: The ability to read odds provides a gambler with insight into how a sportsbook, also known as “Vegas,” views a particular bet. The most common types of odds on sports bets will range from -105 to -115. -115 odds mean that to win $10, a person would need to bet $11.50. Conversely, if the odds are favorable, +115, then a bettor who bets $10 would win $11.50. To calculate ML odds for unfavorable odds, take negative Moneyline odds / (Moneyline odds + 100) * 100 = Implied probability. So, if the odds are -115, then 115/(115+100)*100 = 53.5%.

Betting against the spread: Betting against the spread (“ATS”) means you are taking Purdue -4.5 (-4.5 in my example above; obviously, this number would change week to week) or, hypothetically, the other team +4.5. To cover the spread betting on Purdue, Purdue needs to win by five or more.

Cover: This means a team won ATS. If Purdue beats the hypothetical team above by 1, Purdue has won the game, but Purdue did not cover.

Money line: Money line (“ML”) is the odds given on a particular team to win outright. Payouts can be significantly more or less than betting the spread. For example, betting on a big favorite to win on ML will not yield a very high return. Conversely, betting on a big underdog to win could sometimes pay out double or even triple your original bet. It all depends on the odds.

Over/Under: Over/unders are a type of bets that refer to how many total points will be scored in a game. For example, if the sportsbook sets an over/under of 49, bettors will bet under if they believe fewer than 49 points will be scored and vice versa.

Sharp Bettor: A sharp bettor is a bettor who has shown the ability to turn a profit over the long run. These are generally gamblers who have demonstrated a history of success. Sharp bettors are very useful in identifying value in a particular bet.

Juice: Juice may be the most confusing aspect for new gamblers or those unfamiliar with gambling. In simple terms, juice is the percentage sportsbooks take on a given wager. Sportsbooks use juice to make their profit. To do this, odds for a bet with a sports book usually are -115 or -110 for both sides of the spread. To win $10, you need to be $11.50. That means either way, the sportsbook is gaining a profit because each side is losing $1.50 per bet. This is the juice.
