Odds and Ends: Week 10

Adam Harstad's Odds and Ends: Week 10 Adam Harstad Published 11/10/2022

Gambling on the NFL is big business, especially after a 2018 Supreme Court decision striking down a federal ban on sports betting. Recent estimates suggest that as many as 46.6 million people will place a bet on the NFL this year, representing nearly one out of every five Americans of legal gambling age. As a result, there's been an explosion in sports betting content, most of which promises to make you a more profitable bettor. Given that backdrop, it can be hard to know who to trust.

Fortunately, you can trust me when I promise that I'm not going to make you a more profitable sports bettor. And neither will any of those other columns. It's essentially impossible for any written column to do so, for a number of reasons I detailed here. (I'm not saying it's impossible to be profitable betting on the NFL, just that it's impossible to get there thanks to a weekly picks column.)

This column's animating philosophy is not to make betting more profitable but to make betting more entertaining. And maybe along the way, we can make it a bit less unprofitable in the process, discussing how to find bets where the house's edge is smaller, how to manage your bankroll, and how to dramatically increase your return on investment in any family or office pick pools (because Dave in HR and Sarah in accounting are much softer marks than Caesar's and MGM).

If that sounds interesting to you, feel free to join me as we discuss the weekly Odds and Ends.

Let's Talk About Those Lines

Every week in this space, I provide a table of "lines I'm seeing". I've discussed in the past how useless this is in practice for a picks column; Vegas can shade the odds on a given line to make it a better or worse bet than the spread itself would suggest, and if they cared about me (they certainly don't), they could even change lines in response to any inefficiencies I wrote about so by the time you read this column that inefficiency would be gone.

There's another way those lines are misleading, though; it acts like they're a monolith.

I get all of the lines I post here from nflgamedata.com, run by a guy named Lee Sharpe. I use that site because, while many sites want to keep their data in their own little silo, Lee is an open data evangelist; it's not just possible to scrape data from his pages, it's actively encouraged, and he goes out of his way to make sure everything keeps working. For someone like me who is working with NFL lines on a weekly basis, that's a massive boon. He even keeps a csv file of all of his data that anyone is free to access at any time.

Lee doesn't set the lines himself; he mostly gets them from Pinnacle sportsbook, but in cases where Pinnacle doesn't offer odds for a particular game, he'll find them from somewhere else. (As an aside, Lee gathers these lines for a "Confidence Pool" game he runs where participants assign confidence levels to specific game outcomes and see if they can outperform the Las Vegas lines. At the moment, just 20 out of 706 users are ahead of Vegas. Last year, 21 out of 982 participants beat Vegas. Only three people have managed it in both years so far. Vegas is very, very difficult to beat.)

But different books will have different lines. One book might have a team at -3 while the other has them at -3.5. Even if two books both have a team at -3.5, maybe one is giving -105 odds on it while the other is giving +105 (meaning a win pays out more money on the latter book than the former). Lines and odds don't vary a ton from one book to the next (if they did, algorithmic betters could place contradictory bets on opposing sites with the most favorable odds for each side and book a small but guaranteed profit). But these small variations are often the difference between a 52% bet and a 53% bet, and that difference is often the margin between a profitable week and an unprofitable week, which is why serious gamblers engage in "line shopping", or hunting for the best deal they can possibly find.

As I've mentioned before, the more of your money Vegas is willing to take on a bet, the sharper you should assume its odds are. That plays out here, too; these variances are much larger on bets with lower maximums. Totals and odds on player props, for instance, can differ quite substantially from one site to the next. Here's an example from September showing Cooper Kupp's estimated chances of scoring a touchdown ranging from 54.5% (-120) all the way up to 66.7% (-200)

Often times books will deliberately add "juicy" odds on a lower-limit bet in the hopes that once you're in the door, you'll make several other more profitable (for them) bets as well. But the end result is that a substantial percentage of gambling profitably is just constantly shopping around for the best odds you can buy.

For recreational gamblers like us, it's not as big of a deal; we're losing money in the long run, but hopefully, we're having fun doing it. But it might at least be worth keeping two or three different sportsbooks or betting apps handy and looking for the best odds you can find between them.

Revenge Game(s) of the Week

Just like we knew they would, both Taylor Heinicke and the Chicago Bears successfully achieved revenge by losing by a marginally smaller total than they were expected to (in this case, they lost by 3 points each while getting 3.5 and 4.5 points, respectively). That's the power of revenge, baby! I'm sure they all feel great about the fact that they didn't lose by two more points. I personally feel great about putting two more "wins" in the Revenge Game Win Column.

Buffalo (-3.5) vs. Minnesota

Before he was an All Pro with the Bills, Stefon Diggs was most famous for his vague, often cryptic tweets on the Vikings with no obvious precipitating cause. The thing about Twitter is they get it in Buffalo, too, and Bills fans are now getting their own taste of Cryptic Diggs.

Hopeful Bills fans have latched onto this as a secret hint that Josh Allen, who is nursing an elbow injury, might be healthy enough to play this weekend. Vikings fans are just laughing at the folly of trying to read sense into Diggs' timeline. The thing is, for our purposes, it doesn't really matter if Allen plays or not. Sure, Allen is on the very short list of best quarterbacks in the NFL. But his backup is Case Keenum, another former Viking, so if Allen can't go, that just turns this into a rare double-revenge game and makes me even more confident about the pick. 3.5 points is an exceptionally small total to lay for that possibility.

Cleveland (+4) at Miami

The Browns may be 3-5, but their offense with backup quarterback Jacoby Brissett has been one of the best in the league thanks to an elite rushing attack and timely passing to Amari Cooper. Brissett only has a few weeks left before his scheduled return to the bench, but before that at least he gets a chance to return to Miami (where he started five games last year) and wonder what he could be doing these days if he had Mike McDaniel, Tyreek Hill, and Jaylen Waddle on his side, instead. The grass is always greener on the other side. Or, in this case, I suppose it's tealer. More teal? Either way, I'll take the Browns and the points.

The "Let's Hope Our Next Pick Isn't Going To Hire a High School Coach" Lock of the Week

I said last week that the "Time for New Orleans to Lose Me Some Money Again" Lock of the Week was 4-0, which meant even a couple consecutive losses would leave me with a strong record, which meant that the name was going to stick around for a while. Well, then the Random Number Generator picked the Colts, who played so atrociously that they fired their head coach and hired some guy who went 20-16 with Hebron Christian Academy in Dacula, Georgia. And I can't help but think that this is somehow entirely our fault. I don't want that kind of power, so we're changing it up again.

LA Chargers (+6.5) at San Francisco

The Chargers have been underperforming expectations this season with a negative point differential thanks to a couple of blowout losses and a lot of closer-than-expected wins against bad teams. And head coach Brandon Staley has a reputation for making the type of aggressive 4th-down decisions that dominate the news cycle when they don't work out. But, per the analytics, Staley's actually been one of the more conservative head coaches in the league on 4th down this year, and the Chargers are 5-3, so even with a loss, they'll still have a winning record. Which is my way of saying I don't think they're going to fire Staley next week and replace him with some random high school football coach. But then again, I didn't exactly think the Colts would, either, and everyone knows the NFL is a copycat league.

Either way, the random number generator likes the Chargers and the points, and I want to give it a chance to redeem itself.
