The following NBA betting trends are a collection of analytical data, betting systems and strength ratings featured on VSiN and qualified for the NBA playoff games on 5/15. This report is meant to emulate the process that Steve Makinen and other members of the VSiN Analytics team undergo when handicapping each day’s NBA board.

AJ’s Angles

These are the top NBA betting trends and systems for the games, handpicked by VSiN Analyst AJ Makinen.

* Close losses have been galvanizing for teams lately in the second round, as those losing by 6 points or fewer in one game follow that up with a 22-10 SU and 23-9 ATS (71.9%) record over the last five postseasons.
Trend Match (PLAY): DETROIT (+3.5 at CLE)

* #2 seeds have not closed out opponents well in the second round, going just 6-14 SU and 4-16 ATS (20%) when given that chance since 2018.
Trend Match (FADE): SAN ANTONIO (-4.5 at MIN)

* Over the total has converted in eight of the last ten meetings between Minnesota and San Antonio
Trend Match (PLAY OVER): SAS-MIN (o/u at 218.5)

Trends by Line/Total Range

Laying big points with home teams has not worked out well for bettors in the second round recently, as hosts laying 8.5 points or more have gone 23-12 SU but just 12-23 ATS (34.3%) since 2016! This is in direct contrast to the first round numbers we saw a couple of weeks ago. All other home favorites are 77-54-1 ATS (58.8%) in that span.
Trend Match (PLAY): CLEVELAND (-3.5 vs DET)

Second round smaller road favorites of -4.5 or fewer (or pick ’em) have struggled over the last decade-plus, having gone 17-25 SU and 15-27 ATS (35.7%) since 2013.
Trend Match (FADE): SAN ANTONIO (-4.5 at MIN)

Last Game Trends

Teams have struggled in the second round when coming off same series losses and playing on the road, having gone just 15-33 SU and 19-29 ATS (39.6%) in the follow-up contests in their last 48 playoff tries.
Trend Match (FADE): DETROIT (+3.5 at CLE)

Teams coming off a loss in a second round series game and playing at home have bounced back well, 38-22 ATS (63.3%) since 2021.
Trend Match (PLAY): MINNESOTA (+4.5 vs SAS)

Close losses have been galvanizing for teams lately in the second round, as those losing by 6-points or fewer in one game follow that up with a 22-10 SU and 23-9 ATS (71.9%) record over the last five postseasons. Furthermore, outright winners are 31-1 ATS in these games, meaning they have been decisive.
Trend Match (PLAY): DETROIT (+3.5 at CLE)

There is a very interesting totals trend that has developed lately in competitive contests, as when games have been decided by 10 points or fewer, the follow-up second round same series game is 41-30-1 Under (57.7%) the total in the last 72.
Trend Match (PLAY UNDER): DET-CLE (o/u at 209.5)

Trends by Game Number

Game 6s have swung towards underdogs, 16-14 SU and 19-11 ATS (63.3%) since 2014.
Trend Matches (PLAY ALL): DETROIT (+3.5 at CLE), MINNESOTA (+4.5 vs SAS)

Trend Match (FADE): CLEVELAND (-3.5 vs DET)

Teams looking to close out a series in game 6 have struggled, going just 10-14 SU and 9-15 ATS (37.5%) in their last 24 opportunities, including 5-6 SU and 3-8 ATS (27.3%) as chalk.
Trend Matches (FADE ALL): SAN ANTONIO (-4.5 at MIN), CLEVELAND (-3.5 vs DET)

Schedule Situations Crucial for NBA Handicapping

The following is an expanded version of the article published in this year’s VSiN NBA Betting Guide, detailing scheduling situations in which teams have shown definitive patterns over the last few seasons. Typically, there are reasons that teams perform at varying levels based on their schedules, whether that be from the amount of rest they’ve gotten before a game, how fatigued they are from a string of games, or how they deal with injuries/workloads based on the schedule pressures.

* DETROIT is 12-5 SU and 13-4 ATS (76.5%) as an underdog this season
* CLEVELAND is just 26-27 SU and 18-35 ATS (34%) vs. teams that have winning records right now this season

Strategies Using NBA DraftKings Betting Splits Data

One of the most touted features on the VSiN.com website, and a feature that we believe to be a fantastic resource for bettors, is the betting splits pages. These are the pages that we have built utilizing the data that DraftKings so graciously provides to us, detailing the breakdowns of the money and ticket splits for point spreads, money lines, and totals. 

In an article published on the VSiN.com website on opening day, Steve Makinen outlined 14 different systematic strategies for successfully using the DK Betting Splits Data that were developed in the last three seasons. Here are the systems and qualifying plays for the games as of 12:00 PM ET on Thursday. These can and will change, so continue to track and qualify the systems up until tip-off for best usage.

To summarize the findings from the first half data of the 2025-26 season, the sample contained 633 games, and for the most part, majority bettors have lost on all six point spread, money line, and total categories. In fact, this has been the worst half-season they have endured since I started studying this subject a few years ago. Here are the results:

– Majority handle on point spreads: 291-335 ATS (46.5%), -77.5 units – ROI: -12.4%
– Majority number of bets on point spreads: 287-323 ATS (47%), -68.3 units – ROI: -11.2%
– Majority handle on money lines: 379-247 (60.5%). -123.2 units – ROI: -20.2%
– Majority number of bets on money lines: 404-227 (64%). -113.7 units – ROI: -18%
– Majority handle on totals: 306-310 (49.7%). -35 units – ROI: -5.7%
– Majority number of bets on totals: 307-318 (49.1%), -42.8 units – ROI: -6.8%

DK NBA Betting Splits system #2: When 59% or more of the handle has been on the road side of an ATS wager, this “super” majority group has gone 868-785 ATS (52.5%) over the last 3+ seasons. This has produced a profit of +4.5 units and an ROI of 0.3%. This has been a very consistent system since I first found it, and for its simplicity, fairly successful. However, it is down over 20 units so far in 2025-26, so perhaps tread lightly. Even still, remember that handle is the total amount of money on a game and is generally considered sharper. When a good portion of the overall money is on a road team in the NBA, it wins more often than not.
System Match (SLIGHT PLAY): SAN ANTONIO

DK NBA Betting Splits system #4: In another somewhat rare situation, when there was a majority handle backing the team with fewer wins on the season in the NBA over the last 3+ seasons, that group produced a 456-412 ATS record (52.5%), good for +2.8 units of profit and an ROI of 0.3%. This is another system that has dropped a bit this season but has still outperformed the normal levels by a decent amount. We’ll see if it can stay positive in the second half of the season.
System Match (SLIGHT PLAY): CLEVELAND

DK NBA Betting Splits system #7: The number 63% or higher has been a key super-majority number in non-divisional conference games over the last 3+ seasons, with handle groups of that size boasting a 579-508 ATS record, good for 54.2%. This is over a 4% improvement on the overall majority figures and has netted +20.2 units of profit and an ROI of 1.9%.
System Match (PLAY): SAN ANTONIO

DK NBA Betting Splits system #10: Majority handle money line wagerers have struggled in each of the last three playoff seasons, with handle majorities going 149-110 for -44.87 units and an ROI of -18%. Compare this to the usual ML return of just over -5%, and you can see bettors are losing on a lot of favorite plays.
System Matches (FADE ALL): CLEVELAND ML, SAN ANTONIO ML
