Ranking the Top Five Defenders in OKC Thunder History

The Oklahoma City Thunder have had elite defensive players throughout their short time in OKC. Who are the best at their craft?

The Oklahoma City Thunder have created a culture of physical defense throughout the franchise's time in Oklahoma City. Each iteration of the team has had a gritty style with at least one elite defender, from the beginning with Serge Ibaka protecting the rim to now with Chet Holmgren rising each season.

The Thunder have enough elite defenders in their history to make ranking them difficult. Between a mixture of elite rim protectors and unbeatable on-ball forwards, these five are the best defenders in franchise history.

5. Lu Dort

Defense was how Luguentz Dort was able to break through as an NBA player coming into the league as an undrafted free agent from Arizona State. He worked his way through the rotation at high speeds in his first year, never looking back the second he was first named a starter throughout his entire seven-year Thunder career.

Dort was consistently among the best, if not the best, point-of-attack defender in the league every season with the team, finally getting the All-Defensive recognition he deserved in 2024-25, the same year OKC won its first title. He excelled in matchups against scoring-focused guards and constantly sized up to take on every guard/forward No. 1 option in the Association.

The fact that Dort is the first name on the list shows how deep OKC's defensive history goes.

4. Jalen Williams

Jalen Williams and Dort are very close when it comes to the defensive end, but Williams's versatility takes him over just slightly. He was given All-Defensive Second Team honors in his last fully healthy season in 2024-25, but definitely deserved Defensive Player of the Year shouts.

Williams can guard all five positions at a high level and excels at reading the passing lanes. His 7-foot-2 wingspan allows him to consistently size up opponents; he has started multiple games at center in his career and excelled.

Now, because of Dort's trade to Atlanta, the Santa Clara product will have to extend his defensive workload once again. His talent makes him more than ready for it.

3. Andre Roberson

Before going down with a career-altering patellar tendon rupture in 2018, Andre Roberson was the best defensive player in the NBA. He was on pace to challenge the immovable Rudy Gobert for his DPOY throne, anchoring a Thunder defense that fell apart in his absence.

Roberson made just one All-Defensive Team in his career, also placing fifth in DPOY voting the season before his injury, but everyone who witnessed his peak understands just how elite he was on that end.

The Colorado product could guard all positions, shutting down every superstar in the league throughout the 2010s. Despite being a net-negative offensive player, Roberson stayed on the floor due to his otherworldly defensive talent.

2. Serge Ibaka

Ibaka was the franchise's first true rim protector, leading the league in blocks on two separate occasions, making an All-Defensive team for three consecutive years from 2011-14. The native of the Republic of the Congo anchored the first contending teams in the Thunder's history, averaging 2.5 blocks per game through his seven-year tenure.

Hence his nickname "Iblocka," the big man was frightening for any rim-runner to go against. Despite never winning a DPOY trophy, he's finished in the top five in voting three separate years, finishing second behind Tyson Chandler in 2012.

Despite anchoring an era, one current Thunder has passed him.

1. Chet Holmgren

As a three-time block champ and All-Defensive team member, statistically, Ibaka is the best defender in franchise history and definitely could still be considered so, but Holmgren just edges him out. Just three years into his career, he's already finished second in DPOY voting (similarly to Ibaka), as well as reaching an All-Star Game.

Holmgren is incredibly versatile on defense, being difficult to find a mismatch against, constantly guarding wings to roam off of, using his unreal 7-foot-6 wingspan to make difficult recoveries look simple.

In an era focused on perimeter shooting, Holmgren has been able to catch up to some of the rim-protecting records set by Ibaka as well. Still yet to reach his prime, Holmgren is the franchise's best chance to take home a DPOY.
