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 5/12 and 5/13. 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 today’s games, handpicked by VSiN Analyst AJ Makinen.

* Winning doesn’t provide a whole lot of momentum for the second round teams seeded fifth or worse, as they are just 14-24 SU and ATS (36.8%) when coming off a same series victory since 2013.
Trend Match (FADE): MINNESOTA (+10.5 at SAS)

* Teams that lost big in Game 4, by seven points or more, come back very competitively in Game 5, going 16-10 SU and 19-7 ATS (73.1%) in their last 26 tries.
Trend Match (PLAY): DETROIT (-3.5 vs. CLE)

* DETROIT is 21-10 Under the total (67.7%) as a favorite of -1.5 to -5 points this season
Trend Match (PLAY UNDER): CLE-DET (o/u at 212.5)

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 22-12 SU but just 11-23 ATS (32.4%) since 2016. This is in direct contrast to the first-round numbers we saw a couple of weeks ago. All other home favorites are 77-53-1 ATS (59.2%) in that span.
Trend Match (FADE): SAN ANTONIO (-10.5 vs. MIN)
Trend Match (PLAY): DETROIT (-3.5 vs. CLE)

Last-Game Trends

Teams coming off a loss in a second-round series game and playing at home have bounced back well, 37-21 ATS (63.8%) since 2021.
Trend Matches (PLAY ALL): SAN ANTONIO (-10.5 vs. MIN), DETROIT (-3.5 vs. CLE)

Close losses have been galvanizing for teams lately in the second round, as those losing by six points or fewer in one game follow that up with a 21-10 SU and 22-9 ATS (71%) record over the last five postseasons. Furthermore, outright winners are 30-1 ATS in these games, meaning they have been decisive.
Trend Match (PLAY): SAN ANTONIO (-10.5 vs. MIN)

A very interesting totals trend 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 41-28-1 Under (59.4%) the total in the last 70.
Trend Matches (PLAY UNDER ALL): MIN-SAS (o/u at 218.5), CLE-DET (o/u at 212.5)

Poor 3-point shooting teams don’t necessarily bounce back from those off nights, going 26-30-1 ATS (46.4%) after games in which they shot 25% or less.
Trend Match (FADE): SAN ANTONIO (-10.5 vs. MIN)

Trends by Game Number

Expect Game 5s to be tight: Favorites are 34-13 SU but just 22-25 ATS (46.8%) since 2013. This is a significant win/no cover percentage of games. In these contests with lines of 5.5 points or more, they are just 12-19 ATS (38.7%).Trend Match (FADE): DETROIT (-3.5 vs. CLE)

Teams that lost big in Game 4, by seven points or more, come back very competitively in Game 5, going 16-10 SU and 19-7 ATS (73.1%) in their last 26 tries.
Trend Match (PLAY): DETROIT (-3.5 vs. CLE)

Trends by Seed Number

No. 1 seeds are on a 19-8 SU and 17-10 ATS (63%) at home in the last 5+ seasons in the second round, turning around a trend that saw them go just 9-8 SU and 5-11-1 ATS (31.3%) prior.
Trend Match (PLAY): DETROIT (-3.5 vs. CLE)

Teams seeded No. 4 tend to be overmatched in the underdog role, owning a record of 18-46 SU and 26-37-1 ATS (41.3%) as such since 2015.
Trend Match (FADE): CLEVELAND (+3.5 at DET)

First-round upset winners are also brutal as large underdogs, as teams seeded fifth or lower have gone 5-36 SU and 16-25 ATS (39%) when playing as dogs of six points or more.
Trend Match (FADE): MINNESOTA (+10.5 at SAS)Winning doesn’t provide a whole lot of momentum for the second round teams “not supposed to be there,” as they are just 14-24 SU and ATS (36.8%) when coming off a same series victory since 2013.
Trend Match (FADE): MINNESOTA (+10.5 at SAS)

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.

* CLEVELAND is just 25-27 SU and 17-35 ATS (32.7%) vs. teams that have winning records right now this season
Trend Match (FADE): CLEVELAND (+3.5 at DET)

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 today’s games as of 1 p.m. ET. 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 #1: When 63% or more of the handle was on the side of a home team playing as a four-point favorite or less (or as an underdog) on ATS wager, this “super” majority group has gone 211-174 ATS (54.8%) over the last 3+ seasons, good for +19.6 units of profit and a ROI of 5.1%. This is a fairly profitable system that the public seems to get right consistently. If you see nearly two-thirds of the handle backing a host in an expected competitive NBA game this season, it’s a solid bet to follow it.
System Match (PLAY): DETROIT

DK NBA Betting Splits system #5: Concerning number of bets. When 70% or more of the number of bets has been on the home side of an ATS wager since January 2023, this “super” majority group has gone just 104-142 ATS (42.3%), well below the overall performance of all majorities. This has resulted in a net loss of -52.2 units for an ROI of -21.2%.
System Match (FADE): DETROIT

DK NBA Betting Splits system #8: Naturally, with super majority handles doing well on non-conference and non-divisional conference games as compared to the overall, the area where these groups would figure to struggle would be in divisional games. The super-majority number is a little higher, however, 67% in fact. When this super-majority number has backed a team in divisional games over the last three seasons, they are just 166-189 ATS, good for 46.8%. This is a 3%+ drop compared to the overall majority figures and has resulted in -41.9 units of loss and an ROI of -11.8%.
System Match (FADE): DETROIT

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): SAN ANTONIO ML, DETROIT ML

DK NBA Betting Splits system #11: One of the best, simplest, and most frequent angles I have been able to uncover is when a majority of handle bettors were backing the Under in an NBA game. It is generally believed that most NBA bettors prefer taking Overs. When any majority number has favored the Under option over the last 3+ seasons, the results have been strong, with Under the total on these games going 484-393, good for 55.2%, +51.7 units, and an ROI of +5.9% since January 2023.
System Match (PLAY UNDER): CLE-DET
