One of the many players who starred in the Big Ten over the last four years, Trey Kaufman-Renn, leaves quite a historic resume behind at Purdue. His hard work at both ends of the floor, mixed with his heart and determination, made him one of the best post players in the country, especially playing alongside other Purdue great’s like Braden Smith and Fletcher Loyer. Sure, Kaufman-Renn isn’t going to wow you like many other prospects at his position. Still, he deserves a look, no matter if he hears his name called or goes undrafted.
Let’s take a closer look at Trey Kaufman-Renn’s 2026 NBA Draft Profile.
Trey Kaufman-Renn 2026 NBA Draft Profile
College Career
It’s probably pretty clear that when Trey Kaufman-Renn arrived at Purdue, he was going to have to wait his turn. He did as he took a redshirt year during the 2021-22 season. At that time, it was the Zach Edey and Trevion Williams show in the frontcourt. It helped Kaufman-Renn prepare to step into a much larger role the following season. In 2022-23, he saw action in 35 games, while averaging 4.5 points and 1.8 rebounds. It was yet another step in the right direction for the Sellersburg, Ind., native.
It prepared Kaufman-Renn to be the right-hand man in the post alongside Edey for the 2023-24 season. That year saw a lot of massive moments for TKR and Purdue, as the Boilermakers rolled through the Big Ten, winning both the regular season and conference tournaments before making a run to the National Championship Game. Trey started and played all 39 games during that season, boosting his marks up to 6.4 points and 4.0 rebounds per game. It was during the NCAA Tournament that TKR showed how important he was going to be for the next two years, when he put in an 18-point, eight-rebound performance against Utah State.
Going into his junior season, Kaufman-Renn was going to be the focal point in the post, as Edey graduated. He would be joined by another 7-footer, Daniel Jacobsen. However, a leg injury early in the year for Jacobsen quickly made TKR the focal point in the post. He had the best individual season of his career. Kaufman-Renn was named first-team All-Big Ten for the 2024-25 season while averaging 20.1 points and 6.5 rebounds.
Trey Kaufman-Renn returned for his senior season, as he was ready to make one more major run alongside Smith and Loyer. It wasn’t the 20-point scoring a night season for Renn, but he still proved to be very productive at 14.2 points per game. His biggest impact was on the glass, as he averaged nearly nine rebounds per game. He posted 13 games with at least 10 rebounds, including 19 boards in an overtime win at Nebraska. He finished the season on a hot streak, scoring 10 or more points as Purdue won the Big Ten Tournament, before eventually falling in the Elite Eight against Arizona.
Kaufman-Renn finished his Purdue career with 1,655 points and 762 rebounds in 147 career games. He proved to be one of the biggest double-double threats in the Big Ten during his career.
Strengths
Offense
If you’re looking for efficiency, Kaufman-Renn defined it offensively. He always showcased his natural touch around the basket, as he was an excellent finisher from within 17 feet. Whether it was finishing with a dunk, a floater, or a drop step, TKR is simply efficient. A career mark of 60% certainly sets a good precedent for the 6-foot-9, 240-pound forward. Add in the physicality he plays with, and you have a player who can go get the tough baskets. He thrived in the pick-and-roll throughout his career at Purdue. It didn’t hurt that he was playing alongside the best assist man in NCAA history.
If anything, TKR is going to be valuable as a guy who can fit in no matter where he lands, coming off the bench to get a team produce offensively and on the glass. You can never have enough rebounding, and Kaufman-Renn was one of the best at that. He averaged nearly three offensive boards per game during the 2025-26 season. You can bet that catches the eyes of coaches — especially when Purdue was a high-volume three-point shooting team. That’s what will be asked of TKR in the NBA: crash the glass and get second and third chance opportunities.
Defense
Rebounding will be the name of the game for TKR. He proved it throughout his Purdue career. This could be where he makes his living in the pros. He had 202 of his 308 rebounds during his senior season come at the defensive end. He isn’t a natural shot blocker at 6-9, given he was facing seven-footers on most nights, but his 62 steals for his career showed some promise, especially when he’s going to be asked to defend even bigger players in the pros.
He’s a team-first player, so TKR is going to do whatever it takes defensively to help his team. Is he an elite defender? No, but put him next to an All-Star center or atleast center with that ability, and he’s going to thrive.
Weaknesses
Offense
Kaufman-Renn isn’t a shooter; that’s very clear, as he has only attempted 64 career threes. Then again, he showed a little bit of progress from the outside as he got older. It’s not his game, but to have an ability to step out and make some on occasion wouldn’t hurt. Looking at the volume, shooting 28% from deep for his career doesn’t flash.
If he’s going to get to the free-throw line at the rate he was able to in college, Kaufman-Renn will need to continue to work on his free-throw percentage. He shot 62% for his career at Purdue. You can work with that, but in the NBA, he’s going to need to work on getting that mark up over 70%, especially if he grows into more than just a strong bench player.
Defense
TKR doesn’t have a quick step defensively, so he’s going to struggle against more athletic bigs. Another massive question mark for Trey Kaufman-Renn will be his age. He will already be 24 when the 2026-27 season begins, so it begs the question about his future upside. Along with not having the lateral quickness you would hope for, a player with the rebounding ability of Kaufman-Renn can’t switch defensively.
He’s going to have trouble defending the 3-point line. That was one of the biggest pitfalls during his collegiate career. While he has the physicality to match up with guys taller than him, he struggled to guard bigs who can shoot outside the post. That’s going to happen every night in the NBA, so if he can’t adapt, he’s going to have a tough time.
NBA Comparison
Sometimes you see players come along that you expect to make a great pro. Sure, TKR has the resume and abilities to be a key contributor in the league. In fact, he’s similar to a couple of players who were able to provide scoring, but most importantly, rebounding during their NBA careers. The first would be Mike Scott. Scott carved out a nice nine-year NBA career, where he was primarily a bench player, but always provided good minutes.
Scott is a couple of inches shorter than TKR, but he always played bigger than he is. Another good comp would be Montrezl Harrell. If Trey Kaufman-Renn can play at a level anywhere near Harrell, he could have a future Sixth Man of the Year Award on the way. That’s exactly what Harrell proved to be during his NBA career. He won the award during the 2019-20 season, while also having three other seasons in the top-nine in that award race.
Harrell was a 12 and five guy during his eight seasons in the NBA. If a team can grab TKR late in the 2026 NBA Draft, he has a real chance to contribute, as Scott or Harrell did.
