The Thunder's 73-Win Upset: How Oklahoma City Nearly Broke Golden State's Historic Season

This article covers the Thunder's 2016 playoff series against the Warriors, explaining the stakes of that matchup, how Oklahoma City nearly forced a Game 7, and what the series revealed about the NBA landscape at that moment. By the end, you'll understand why this specific matchup mattered to the league and to Oklahoma City's identity as a basketball city.

In May 2016, the Golden State Warriors arrived at Chesapeake Energy Arena carrying a 73-win regular season record, the most wins in NBA history. The Thunder, a year removed from losing Kevin Durant to free agency, faced elimination in the Western Conference Finals. The series became the pivot point of that season: if Oklahoma City won, it would send a 73-win team home and reset the championship narrative. The Warriors won instead, but not before the Thunder demonstrated that regular-season dominance and playoff depth were not the same thing.

The Context: Durant's Departure and the Thunder's Recalibration

Oklahoma City entered the 2015-16 season fundamentally altered. Durant, the franchise centerpiece for nine seasons, had signed with Golden State in July 2015, joining the Warriors just weeks after they'd lost the Finals to LeBron James and Cleveland. His departure left Russell Westbrook and Serge Ibaka as the Thunder's best players. The franchise had spent the summer retooling, acquiring Victor Oladipo, Enes Kanter, and other rotation pieces, but no acquisition could fully replace a generational scorer.

The Thunder still won 55 games that season, good enough for the second seed in the West. Westbrook elevated his game significantly, averaging 23.5 points and 10.4 assists per night. Ibaka remained a defensive anchor. The team played with something resembling desperation, knowing that losing Durant had closed a window that had looked wide open.

When the Thunder faced Golden State in the conference finals, they were the underdogs in the literal sense: the Warriors had just set the wins record that every team in the league measured itself against.

The Series: How Close the Thunder Came

The Thunder took Game 1 at home, 108-101, in a defensive grind that caught Golden State off balance. Westbrook's intensity and the team's willingness to live on the perimeter, shooting three-pointers and attacking on drives, created rhythm problems for the Warriors' switching defense. The victory was not a surprise given Oklahoma City's talent, but it signaled that the series would be competitive rather than coronation.

Golden State responded by winning the next three games, including a decisive 118-94 Game 4 at Oracle Arena in Oakland. The Warriors' offensive firepower became clearer in those games. Stephen Curry, Klay Thompson, and Draymond Green executed pick-and-roll actions that spread the Thunder's defense thin. Oklahoma City's three-point shooting helped keep games close, but Golden State's shooting volume and efficiency eventually wore down the defense.

Game 5 returned to Oklahoma City, and the Thunder won 106-105 in one of the tighter playoff games of the season. Westbrook and the home crowd created an environment where the Warriors' rhythm mattered less than execution in isolation situations. Chesapeake Energy Arena, the 20,000-seat downtown venue that had housed the Thunder since the 2008 relocation from Seattle, generated the kind of defensive pressure that regular season records cannot measure.

With the series at 3-2 in Golden State's favor, the Thunder had a chance to force Game 7 if they won Game 6 in Oakland. They did not. Golden State won 120-111, clinching the series and returning to the Finals.

What the Series Revealed About the Thunder and the 2016 NBA

The Warriors' progress to the Finals (they would beat Cleveland again) validated their regular season. But the Thunder's resistance, particularly at home and in the close games, revealed why Oklahoma City remained a legitimate contender despite losing its best player. Westbrook's emergence as a superstar-level playmaker became visible in this series. He had to shoulder more offensive creation without Durant's off-ball spacing, and he did so.

For Oklahoma City as a market, the series also confirmed something about the franchise's place in the league. The Thunder had moved to Oklahoma City in 2008 from Seattle as the SuperSonics, a relocation that had been controversial but that gave the city an NBA team after 13 years without one. That 2016 playoff run, even in defeat, demonstrated that the franchise had built something sustainable. The Warriors, the Spurs, and the Cavaliers were the league's true powers, but the Thunder could compete at the highest level.

Westbrook would carry that momentum into the 2016-17 season, when he would average a triple-double and lead the Thunder to the first seed in the West. Durant's departure had closed one chapter, but it had also forced the franchise and its centerpiece player to prove themselves differently.

The Practical Takeaway

For anyone tracking the Thunder's history or the broader arc of Golden State's dominance in the mid-2010s, the 2016 series stands as the moment when the Warriors' 73-win season finally met a team that could make them uncomfortable. The Thunder lost, but they showed that a well-constructed roster with depth and a superstar willing to expand his game could compete with the greatest regular season team ever assembled. That lesson shaped how the Thunder approached the next two seasons, and it remains the last time Oklahoma City reached a conference finals.
