NHL weekly betting guide: Which teams are the market's biggest movers?

About 30% of the season has taken place, which seems like a lot until you realize there are more than twice as many games left to go. A lot can change, and teams can float back to their mean.

We know that moneylines are a function of win probability, so let's take a look at who the betting market thinks has changed the most from preseason projections. Teams with a positive percentage are that much better than an average team, while teams with a minus are rated that much below average.

Movin' up

The Rangers and Bruins lead their respective divisions and are on pace for almost 130 points apiece, so it shouldn't be surprising that two teams projected to barely get to 100 points are more highly thought of now. The other two division leaders - Vegas and Colorado - were expected to be there, so their change is marginal.

The Canucks' move from below-average to above-average feels like a bigger deal, but from a betting perspective, it's no different from the Flyers and Coyotes moving closer to league average and the Panthers and Hurricanes moving further above that line.

Fallin' down

It's not shocking that the market has soured on the Sharks, but you'll notice many of the lowest-ranking teams before the season have shown up here. Bettors don't like betting on bad teams, so their perception was naturally going to take a hit.

The Sabres were expected to contend for a playoff spot, but - when factoring in games played - they're essentially dead last in the Atlantic Division.

There are some big names on the list - Lightning, Penguins, and Maple Leafs - who are easy to stomach betting on going forward. You might wonder why the Oilers aren't on this list, but while they have lost bettors money, there's been a consistent belief that they'll turn around any day now, so there aren't any discounts on Connor McDavid's team.

The cheat sheet

The dirty little secret in the betting world is that, while there are no bad bets at the right price, the discovery process of what a good price looks like is hidden.

Each week, we balance market information from regular-season point totals and in-season advanced metrics - with an even-strength focus - to determine the win probability for each team and the moneyline needed to bet on either side. The idea is to remove the cognitive bias of win-loss records, which can be skewed by outliers like special-team results, poor goaltending performances, and other unreliable events.

You can use whatever parameters you like to decide how much of an edge you need to trigger a bet, but here are mine:

• True line favorite of -111 or longer: 1%
• True line between -110 and +110: 2.5%
• True line underdog of +111 or longer: 4%

I also have a 5% win probability consideration for a team playing in the second game of a back-to-back with travel and a 3% consideration for the second leg of a home back-to-back. When it comes to injured players, an estimation is made on the player's impact on their team's win probability.

When the betting markets open up the night before, you can compare those prices with our "price to bet" column to see if you're getting any value with either side's moneyline. There's a possibility that a moneyline moves into a bet-friendly range at some point between the market opening and puck drop.
