ASA’s 2025 NBA Finals Betting Preview: Why the Oklahoma City Thunder Will Win in 5 Games (+230) Over the Indiana Pacers

As the 2025 NBA Finals tip off on June 5, the Oklahoma City Thunder face the Indiana Pacers in a matchup that pits the league’s most dominant team against a scrappy, high-octane underdog. The Thunder, who posted a historic 68-14 regular season, are heavy favorites to claim their first NBA championship since the franchise’s Seattle SuperSonics days in 1979. One intriguing betting opportunity stands out: the Thunder to win the series in five games at +230 odds. This article dives into the statistical case for OKC’s dominance, highlighting their regular-season performance, key metrics, and why they’re poised to dispatch the Pacers efficiently.

Thunder’s Regular-Season Dominance: A Statistical Powerhouse

The Oklahoma City Thunder were a juggernaut in the 2024-25 regular season, finishing with 68 wins, the seventh team in NBA history to reach that mark. Their dominance was particularly evident in their ability to win games decisively, with 54 of their victories coming by double digits—a testament to their ability to overwhelm opponents. Their average margin of victory (MOV) of +12.2 points per game set a historical standard, reflecting a team that not only wins but does so convincingly. This is a stark contrast to the Pacers, who managed a respectable 50-32 record but posted a modest +2.2 PPG MOV, suggesting closer games and less consistent dominance.

On the road, the Thunder were nearly unstoppable, going 36-11 straight-up (SU) with an average MOV of +7.9 PPG. This road prowess is critical in a 2-2-1-1-1 Finals format, where OKC will need to steal at least one game in Indianapolis. Their ability to maintain a high MOV away from home signals a team that doesn’t falter under pressure, a trait that bodes well for a short series.

Defensive and Offensive Efficiency: OKC’s Elite Two-Way Play

The Thunder’s success is anchored by their elite two-way play, ranking 1st in defensive efficiency (1.075 points allowed per possessions) and 3rd in offensive efficiency (1.204PPP) during the regular season. Their playoff defensive efficiency remained stellar at 1.062, showcasing their ability to clamp down on opponents even in playoff games. OKC’s defense is a turnover-forcing machine, averaging 18.0 turnovers forced per game in the playoffs, converting those into 23.8 points per game. This disruptive style, led by All-Defensive talents like Jalen Williams, Luguentz Dort, and Alex Caruso, plus rim protection from Chet Holmgren (2.0 blocks per game), makes OKC a nightmare for opposing offenses.

In contrast, the Pacers ranked 9th in offensive efficiency and a middling 13th in defensive efficiency during the regular season. While Indiana’s playoff offense has been electric—posting a 118.1 offensive efficiency rating, second only to the Cleveland Cavaliers—their defensive efficiency rating of 113.9 exposes vulnerabilities against a team like OKC, which thrives in chaos and transition. The Pacers’ fast-paced style (98.4 pace) plays into the Thunder’s hands, as OKC’s 100.6 pace and league-leading transition defense (allowing just 9.1 transition points per game) neutralize Indiana’s preferred track-meet tempo.

Head-to-Head Matchups: Thunder’s Regular-Season Sweep

The Thunder swept the Pacers in their two regular-season meetings. On December 26 in Indianapolis, OKC overcame a 15-point deficit to win 120-114, with Shai Gilgeous-Alexander dropping 45 points on 15-of-22 shooting. The March 29 rematch in Oklahoma City was a rout, with the Thunder cruising to a 132-111 victory, fueled by 17 three-pointers (47.2% from deep) and 58 points in the paint. These games highlighted OKC’s ability to exploit Indiana’s defensive weaknesses, particularly in transition and perimeter defense, where the Pacers allowed opponents to shoot 34% from three in the regular season compared to OKC’s league-leading 33% in the playoffs.

Key Matchups and X-Factors

The Finals hinge on the battle between Indiana’s high-powered offense, led by Tyrese Haliburton and Pascal Siakam, and OKC’s suffocating defense. Haliburton struggled mightily against the Thunder in the regular season, scoring just 4 points in the first meeting and 18 in the second, with usage rates well below his 21.6% season average. OKC’s strategy of deploying Dort and Cason Wallace to shadow Haliburton disrupted his rhythm, forcing the ball out of his hands. With Indiana’s offense relying on Haliburton’s playmaking (2.2 assist-to-turnover ratio in the playoffs), OKC’s ability to limit him could cripple the Pacers’ attack.

On the other end, Shai Gilgeous-Alexander, the 2024-25 MVP, is a matchup nightmare. Averaging 32.7 PPG on 52/38/90 shooting splits in the regular season and 29.8 PPG in the playoffs, SGA’s ability to draw fouls (7.9 points per game at the free-throw line) exploits Indiana’s weakness in opponent free-throw rate (15th among playoff teams). Andrew Nembhard, tasked with guarding SGA, allowed 27 points on 11-of-18 shooting in their regular-season matchups, suggesting the Pacers lack an answer for OKC’s superstar.

The rebounding battle also favors OKC. Chet Holmgren and Isaiah Hartenstein are double-digit rebound threats, while Indiana’s Myles Turner averages a modest 5.8 rebounds per game in the playoffs. The Thunder’s ability to control the glass and limit second-chance opportunities could further tilt the possession battle, where OKC led the league with a +435 turnover differential in the regular season.

Why Thunder in 5 (+230) Makes Sense

The +230 odds for the Thunder to win in five games reflect a series where OKC’s dominance is expected but not guaranteed to be a sweep. The Pacers’ potent offense and home-court resilience (they went 4-2 at home in the Eastern Conference playoffs) suggest they could steal one game, likely in Game 3 or 4 in Indianapolis

Betting Recommendation

The Thunder’s historic regular-season performance, elite two-way efficiency, and head-to-head success against the Pacers make them the clear favorites. Their ability to win big (54 double-digit victories, +12.2 MOV) and perform on the road (+7.9 MOV) supports a quick series. At +230, betting on OKC to win in five games offers value, balancing their dominance with the likelihood of Indiana stealing one game at home.

NBA Finals Prediction – Efficiency Champion – 4/19/24

NBA Championships based on Math!

By – ASA

So, you’re thinking about a future wager on the NBA Championship and you’re not sure who to take? We can help you with some proven statistics that may accurately predict who this year’s Champion may be and rule out the most obvious media darling pretenders.

The backbone of this research is centered around efficiency ratings/rankings compiled through the regular season and is a tool I first discovered in the early 2000’s. Since then, I have seen several variations of my original work from other experts in the field, but here is the authentic version.

The average overall efficiency rating this season in the NBA was 1.153 points scored/allowed per possession. The Boston Celtics were the most efficient offense in the NBA at 1.232 points per possessions while the Minnesota Timberwolves held the best defensive efficiency rating in the league of 1.090 points allowed per/possession.  If past history tells us anything, these numbers can be extremely useful in predicting this year’s eventual NBA Champion.

This trend started in 2008-09 when the Finals featured the LA Lakers with head coach Phil Jackson and HOF’er Kobe Bryant, facing the Orlando Magic and a young Dwight Howard. The Lakers won that Finals series in dominating fashion 4 games to 1.  The Lakers finished the regular season ranked 3rd in offensive efficiency ratings (OEFF) and 6th in defensive efficiency (DEFF). Orlando had efficiency numbers that ranked them 12th in OEFF and 1st in DEFF. This was the beginning of the “efficiency” NBA Champions.

Below are the NBA Finals Champions and their overall efficiency rankings for the past 15 Championships.

NBA CHAMPIONS FROM 2008 on and OEFF/DEFF regular season efficiency rankings:

2008-09 LA Lakers (OEFF = 3rd, DEFF = 6th)

2009-10 LA Lakers (OEFF = 11th, DEFF = 4th)

2010-11 Dallas Mavericks (OEFF = 8th, DEFF = 7th)

2011-12 Miami Heat (OEFF = 8th, DEFF = 4th)

2012-13 Miami Heat (OEFF = 1st, DEFF = 9th)

2013-14 San Antonio Spurs (OEFF = 7th, DEFF = 3rd)

2014-15 Golden State Warriors (OEFF = 2nd, DEFF = 1st)

2015-16 Cleveland Cavaliers (OEFF = 3rd, DEFF = 10th)

2016-17 Golden State Warriors (OEFF = 1st, DEFF = 2nd)

2017-18 Golden State Warriors (OEFF = 3rd, DEFF = 11th) 

2018-19 Toronto Raptors (OEFF = 5th, DEFF = 5th)

2019-20 LA Lakers Covid (OEFF = 11th, DEFF = 3rd)

2020-21 Milwaukee Bucks (OEFF = 6th, DEFF = 10th)

2021-22 Golden State Warriors (OEFF = 16th, DEFF = 2nd)

2022-23 Denver Nuggets (OEFF 5th, DEFF = 13th)

EFFICIENCY RATINGS MATTER

You can see for yourself that there have only been two teams that have won a Championship in the last fifteen years that had an (offensive efficiency) OEFF or (defensive efficiency) DEFF NOT in the top 11 for that season. It has been the last two Champs in the Warriors in 21-22 and Nuggets last season.  Every team that has won a Championship in the past 15 Finals has specifically had a Defensive Efficiency ranking in the top 13 at the end of the regular season. 

Using this model (top 11 OEFF and top 13 in DEFF) to predict this year’s Champion we can eliminate everyone but the following teams: Celtics, Thunder, Nuggets, Knicks, Suns and Pelicans. On the outside looking in is Philadelphia who we know played a portion of the season without an MVP type player in Joel Embiid. The Sixers were 13th in OEFF and 11th in DEFF this season. Another team who we pegged prior to the start of the season at +2500 to win it all, who falls outside of this parameter, is the Mavericks. The Mavs rank 10th in OEFF on the season but don’t qualify defensively, ranking 18th in DEFF for the year. But, since the All-Star break the Mavs defense has been infinitely better, ranking 12th in defensive efficiency allowing 1.134PPP.

2023-24 Regular Season Efficiency Rankings for the Math Model “Contenders”

Boston Celtics: OEFF 1st, DEFF 3rd

Oklahoma City Thunder: OEFF 3rd, DEFF 4th

Denver Nuggets: OEFF 5th, DEFF 8th

NY Knicks: OEFF 7th, DEFF 9th

New Orleans Pelicans: OEFF 11th, DEFF 7th

Phoenix Suns: OEFF 9th, DEFF 13th 

Let’s also take into consideration how these teams fared this season against the other top 16 teams in the league. 

Celtics 27-14 SU

Thunder 27-18 SU

T’Wolves 26-19 SU

Nuggets 28-18 SU

Knicks 17-23

Suns 23-22

Intriguing options not on the list! – Dallas Mavericks (+1600) or Los Angeles Clippers (+1600) 

As we mentioned above the Mavericks would make this list if we tabulated stats from the All-Star break on. Dallas made some moves prior to the trade deadline and brought in PJ Washington and Daniel Gafford which improved their defense dramatically. Offensively this team has two of the best players on the planet, Luka Doncic and Kyrie Irving who can each single-handedly take over a game on the offensive end of the court. The Clippers go as far as a healthy Kawhi Leonard can take them. Unfortunately, we don’t know Leonard’s status but “Playoff Kawhi” is as good as any player historically in the NBA in the postseason. L.A. is loaded with All-Star level talent with Paul George, James Harden, Russell Westbrook along with Leonard and it wouldn’t surprise us to see them in the Finals. The Clippers ranked 4th in Offensive Efficiency this season but were 16th defensively. 

Our Money is on the favorite…BOSTON CELTICS *We had Boston prior to the start of the season at +380*

Everyone talks about a “Big 3” when it comes to NBA Super Teams, but you could argue that the Celtics have a “Big 5” with a starting lineup that includes: Jaylen Brown, Jayson Tatum, Kristaps Porzingis, Jrue Holiday and Derrick White. Let’s not forget to mention the Celtics bench with Sam Hauser, Al Horford, Luke Kornet and Payton Pritchard, just to name a few, who helped Boston have the best bench Net Rating in the NBA at +6.2.  

As we previously mentioned, the Celtics had the best record in the NBA against the top 16 teams in the league this season at 27-14. They ranked 1st in OEFF and 3rd defensively. The Celtics had the best average Margin of Victory per game at +11.3 overall. Boston won at home by an average of +15.2PPG and had a road average differential of +7.5PPG, all best MOV’s in the league. The Celtics have the advantage of home court throughout the Playoffs where they were near unbeatable. They were 20-4 SU versus other playoff teams on their floor this season. Boston may not have to face either Joel Embiid or Giannis Antetokounmpo in the Eastern Conference Finals, and even though the Knicks qualify for an Efficiency Championship, we don’t think they are deep enough to beat the Celtics in a 7-game series. 

Overall, this shapes up to be one of the best NBA playoffs in a long time and we can’t wait! Best of luck with all your wagers.
