Pistons’ Isaiah Stewart making a case for NBA’s best defensive player
DETROIT — Each time Cade Cunningham steps onto the floor, his talents put him up against the best defenders the league has to offer. On a nightly basis, Cunningham focuses on maintaining his All-NBA status against numerous defenders, but he is “thankful” that he doesn’t have to account for Isaiah Stewart.
Cunningham has been teammates with Stewart since the Detroit Pistons drafted him as the No. 1 pick in 2021. Over the years, he has watched as Stewart established himself as one of the league’s premier defenders.This season, Stewart’s defensive production has been a central part of the Pistons’ best start in 20 years. With a 19-5 record, Detroit ranks fourth in the league in defense, posting a net rating of 111.3 while holding opponents to 113.3 points per game. The Pistons’ defensive success has been a collaborative effort, but no player has been at the forefront of the team’s defense than Stewart.
“He has always been big-time. I played against him in high school, and he was always a presence down there,” Cunningham said. “We have put Stew in so many positions and made him have to figure it out, and he always does. His feel for the game and IQ are super slept on. He just knows where to be and when to be there. That’s why he can make so many plays.”
Stewart is an elite defender, demonstrating the versatility necessary for today’s NBA. He is a big man who can switch on ball and defend guards out on the perimeter, while his hustle and activity help the Pistons get stops through deflections and 50-50 balls.
He has shown every attribute that has led his teammates to campaign for Defensive Player of the Year honors. In November, Stewart was a finalist for Eastern Conference Defensive Player of the Month — an award that went to the Toronto Raptors’ Scottie Barnes.
However, no defensive skill set has been displayed more prominently than Stewart’s ability to protect the rim. His shot-blocking has led coach J.B. Bickerstaff to deem Stewart as “the best defensive center in the league.”
“It means a lot because he sees it every single day,” Stewart said. “He knows how much I care about defense and how I have a real passion for that side of the ball. He knows that and he appreciates that, and that means a lot to me.”
Not on ‘Beef Stew’
Stewart had a career year on the defensive end last season. He registered a career-high 1.4 blocks per game and led all reserves in the category while ranking 11th league-wide. However, 24 games into this season, Stewart is on the trajectory to surpass last year’s success.

He is currently tied with Alex Sarr for third in the league for blocked shots, averaging 2.0 rejections per game — trailing only Victor Wembanyama (3.6) and Ryan Kalkbrenner (2.4). Stewart has stood out among his peers for his shot-blocking, erasing numerous dunk attempts.
“How much he cares about it. There will never be a shot that goes up that Stew doesn’t contest,” Ausar Thompson said. “So, for him to sacrifice his body, put his body on the line every night — it’s beautiful to watch.”
Stewart, a 6-foot-8 big man, has acknowledged that his stature makes him an easy target for players seeking a quick highlight dunk, but he often wins his one-on-one battles at the rim.
“I feel like some players seek it out, while others get there and then don’t know what to do,” Stewart said. “Then they would usually pass the ball, which helps us out on defense.”
Stewart has rejected a dozen dunk attempts this season, resembling the likes of Ben Wallace during his heyday in Detroit. In the Pistons’ 122-116 victory over the Portland Trail Blazers on Friday, Stewart blocked two dunk attempts, one of which was against Shaedon Sharpe, who has established himself as one of the league’s most gifted dunkers.
The moment occurred midway through the fourth quarter when Sharpe attempted a one-handed dunk over Stewart, who blocked it with the tips of his fingers. The rejected accounted for one of the four blocks Stewart had on the night, marking the fourth time this season he finished a game with four or more rejections.
“He has the best timing in the league. No one time dunks and layups better than he does,” Cunningham said. “It is honestly kind of scary. It is almost like he has finger tips made of vibranium … I think he is the best defensive player in the league.”
Stewart’s rim protection is a testament to his fearlessness of ending up on the wrong side of the highlight, but it is also an example of his ability to apply the lessons he learned throughout his six-year career. There was a time when Stewart found himself on the wrong end of a poster. Instead of shying away from the moment, Stewart used those experiences to learn how to find his timing and patience.
However, his shot-blocking also demonstrates Bickerstaff’s system. By orchestrating a defensive scheme to get the most out of his players, Bickerstaff quickly realized that Stewart had the intangibles to serve as Detroit’s most reliable defensive anchor.
“We put a lot of responsibility on them. They have to communicate with everybody, and their job is to protect the rim and the paint,” Bickerstaff said. “If you put guys who have the talent that these big guys have in those positions, it gives them opportunities to be playmakers, and it gives them the opportunities to dictate how games go.”
Stewart had a seamless transition when adapting to Bickerstaff’s technique last year. He felt Bickerstaff’s philosophies played to his strengths, which demand physicality, rebounding, rim protection and screen setting.
He has since catapulted up the list as one of the NBA’s best defenders, with the potential to receive some form of league recognition come mid-May.
“He is the most versatile center as a defender in the league. There is not a guy out on the perimeter or the post that he cannot guard,” Bickerstaff said. “He means so much to us because he is the guy who has to erase things, cover up things, and he takes on so many assignments. There are so many things that we ask him to do. I am hard-pressed to find a better defensive center than him in the league.”
