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 13-5 SU and 14-4 ATS (77.8%) as an underdog since the start of last season
Trend Match (PLAY): DETROIT (+1.5 vs BOS)

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 11:00 am 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 full 2025-26 season, the sample contained 1,322 games, and the side categories were almost identical to 2024-25, meaning we should be continuing to see great results for all or most of the systems we’ve continued to track. The total numbers were much worse, indicating the public’s successes in the 2024-25 season may have been a fluke occurrence. In all, four of the six categories showed losses worse than -7% ROI. These were the results:

— Majority handle on point spreads: 653-652 ATS (50%), -64.2 units – ROI: -4.9%
— Majority number of bets on point spreads: 625-652 ATS (48.9%), -92.2 units – ROI: -7.2%
— Majority handle on money lines: 847-458 (64.8%). -131.65 units – ROI: -10.1%
— Majority number of bets on money lines: 894-424 (67.8%). -104.3 units – ROI: -7.9%
— Majority handle on totals: 650-643 (50.3%). -57.3 units – ROI: -4.4%
— Majority number of bets on totals: 636-667 (48.8%), -97.7 units – ROI: -7.5%

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 233-199 ATS (53.9%) over the last four seasons, good for +14.1 units of profit and an ROI of 3.3%.
System Match (PLAY): SAN ANTONIO (+1.5 vs OKC)

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 972-884 ATS (52.4%) over the last four seasons. This has produced -0.4 units and an ROI of about dead even.
System Match (SLIGHT PLAY): BOSTON

DK NBA Betting Splits system #3: It is a somewhat rare situation, but when there was a majority handle backing a home underdog in the NBA over the last four seasons, that group produced a 165-131 ATS record (55.7%). This has netted +20.9 units and an ROI of 7.1%. As a general rule, most bettors tend to bet favorites. This lot of 296 games was only about 6.0% of the total sample size.
System Match (PLAY): SAN ANTONIO (+1.5 vs OKC)

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 672-587 ATS record, good for 53.4%. This is about a 3% improvement on the overall majority figures and has netted +26.3 units of profit and an ROI of +2.1%.
System Matches (PLAY ALL): BOSTON (-1.5 at DET), SAN ANTONIO (+1.5 vs OKC)

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 four seasons, they are just 201-218 ATS, good for 47.9%.
System Match (FADE): NEW YORK (-4.5 vs PHI)

DK NBA Betting Splits system #9: There has been a massive disparity of success levels for majority groups on handle when they back the home or road team on money line wagers. On home teams, these majorities have gone 1722-762 over the last three seasons but for -305.69 units and an ROI of -12.3%. On road teams, these majorities have gone 1,320-869 but for just -53.33 units and an ROI of -2.4%. This near 10% disparity warrants fading ML majorities on home teams consistently.
System Matches (FADE ALL): NEW YORK ML (-180 vs PHI), SAN ANTONIO ML (-110 vs OKC)

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 four seasons, the results have been strong, with Under the total on these games going 545-452, good for 54.6%, +47.8 units, and an ROI of +4.8% since January 2023.
System Match (PLAY UNDER): PHI-NYK (o/u at 232.5)

DK NBA Betting Splits system #12: The average NBA game total since January of 2023 has been a bit over 228. In NBA games with “low” totals, or those less than 220, majority handle bettors have gone an impressive 487-421 (53.6%), while majority number of bets groups are a bit less at 480-437 (52.3%). Both groups have proven winners regardless of which side of the total they have chosen.
System Match (PLAY): OVER – BOS-DET (o/u at 219.5)
