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.
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.

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 & 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 10:45 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 2024-25 season, the sample contained 1,321 games, and for the most part, majority handle bettors were much more successful than majority number of bets groups on point spreads & totals, while both struggled on money lines. The full season performance by the majority handle on totals last year in the NBA was better than any other sport I have covered. In fact, these were the results:
– Majority handle on point spreads: 660-614 ATS (51.8%), -15.4 units – ROI: -1.2%
– Majority number of bets on point spreads: 618-645 ATS (48.9%), -91.5 units – ROI: -7.2%
– Majority handle on money lines: 842-458 (64.8%). -123.18 units – ROI: -9.5%
– Majority number of bets on money lines: 886-421 (67.8%). -137.95 units – ROI: -10.6%
– Majority handle on totals: 708-594 (54.4%). +54.6 units – ROI: +4.2%
– Majority number of bets on totals: 670-621 (51.9%), -13.1 units – ROI: -1%
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 2+ seasons, with handle groups of that size boasting a 494-413 ATS record, good for 54.5%. This is over a 3% improvement on the overall majority figures and has netted +39.7 units of profit and a ROI of 4.4%.
