Rienk Mast - scouting report

Not long ago, I listened to the Backdoor Podcast (I’m a member of the editorial team) podcast called “The Process,” which I encourage you to check out. Luca Virgilio, GM of the Nebraska Cornhuskers, talks about his experience with the team, touching on the historical, political, and cultural context as well. This gave me an interest in following the Nebraska team, and my attention was drawn to a big, blond Dutch big guy who shoots threes like a guard and has the vision of a point guard in the body of a center. In this new scouting report, we take a look at Rienk Mast.

Bio

Rienk was born in Groningen, Netherlands, where he initially started playing korfball (a mix of handball and basketball with the goal of scoring into a basket without a net). He then met coach Marco Van Den Berg, his first coach. From 2017 to 2019, he played for Donar Groningen, debuting at age 16 and also participating in the FIBA Europe Cup, while earning call-ups to the Dutch national team. In January 2019, he decided to move to the United States to attend Bradley University, where he studied physics. Year after year, Rienk improved his averages, going from 8.6 points, 5.8 rebounds, and 1.3 assists in his redshirt freshman season to 13.8 points, 8 rebounds, and 2.4 assists in his junior year.

In 2023, he entered the transfer portal and joined the University of Nebraska under coach Fred Hoiberg. The decision, as Mast himself explained, was driven by the desire to play in the Big Ten and face high-level competition to prove his worth. His impact with the Cornhuskers was very positive (12.3 points, 7.5 rebounds, and 3 assists). In December, he began feeling knee pain that prevented him from jumping and running. He underwent minor surgery to finish the season while playing through the pain, showing great commitment to the team. The real shock came that summer: osteochondritis dissecans (a joint condition in which a portion of the cartilage and underlying bone lose their blood supply). This led to surgery (including the use of cartilage pieces from cadavers) and caused him to miss the entire 2024-25 season.

Mast beat the recovery timeline, and by the start of the 2025-26 season, he was already back on the court. The just-concluded year was historic for both Nebraska and for him. The Cornhuskers finished with a 25-6 record and an excellent 15-5 mark in the Big Ten, returning to the March Madness tournament. They had never won a game in the tournament before, but this year they not only won their first game but reached the Sweet 16 before being eliminated by Iowa. Individually, Mast confirmed himself as one of the most solid big men in college basketball and even recorded a historic triple-double against Florida International with 18 points, 12 rebounds, and 10 assists (the 3rd in school history).

Now Mast has completed his college career and must find a team to begin his professional journey. Let’s take a look at what type of player he is.

Offense

Rienk Mast - shooting chart (Synergy Sports)

Shooting

Mast’s favorite weapon is undoubtedly his outside shooting. We are talking about a true “stretch-big” who can open the floor. For a big man, he has a high volume of 3-point attempts (4.7 3PA with 1.5 3PM). In a preseason game he had 7/8, while in the regular season he had a 6/13 performance in a narrow victory over Michigan State. His shooting mechanics are quick for his position, with a high and very fluid release. The situations he is most involved in are catch-and-shoot and pick-and-pop. However, he has also proven to be dangerous when guarded (1.09 pps) and off the screen despite his size.

Playmaking

The aspect that draws the attention of scouts is the Dutch big man’s great court vision. His 3.1 apg this season are numbers typical of an added playmaker and of a very unselfish player. He can operate as a “hub” for his teammates both from the low post (0.992 ppp) and the high post (1.042 pps). He has a high basketball IQ that allows him to connect with the other big, read excellent cuts, or kick out to shooters on the arc.

Low post

Mast is not just a shooter. He may not be an athletic big man and you won’t see him dunk often, but he knows how to use his size to back down defenders in the post (0.892 ppp). Despite the serious injury, he shows good mobility to spin off the pivot foot and has a soft touch from 3-4 meters to finish with a soft baby-hook.

Offensive rebounding

Despite his athletic limitations, we are still talking about a nearly 6’10” big who can use his height, weight, and good positioning to grab offensive rebounds (2.3 per game). Mast is a fighter who, after the injury, has shown character and the desire to create second-chance opportunities for his teammates.

Cuts

He is an excellent screener who relocates or cuts effectively. Nebraska’s schemes gave him opportunities to make deep cuts or fade away, and he finishes well when left open near the dunker spot (1.561 ppp).

Defense

As mentioned in the offensive section, we are not talking about an elite athlete or an explosive rim protector (0.5 blocks per game in his career). However, he knows how to use his size and bulk effectively in post defense (0.892 ppp allowed).

He can struggle to stay in front of quicker guards during defensive switches or to maintain consistent effort and intensity. He is a solid defensive rebounder and, when focused, adapts well to team strategies such as switching and “swarming.” He can execute deep shows in pick-and-roll situations. He is not the quickest at recovering to his man, but he has shown the willingness to put in extra effort to improve in this area—especially after the injury he suffered.

On top of that, there is something that doesn’t show up in the stats: despite his young age, Mast has a great work ethic and is an excellent communicator both on and off the court. Coach Hoiberg has repeatedly emphasized how important it was to have him back to lead his teammates on both ends of the floor and how he always had the right words in the locker room.

“What Rienk Mast went through -- I've talked a lot about how disciplined he is. He's the most disciplined human being I've ever been around in my life, and I'm so happy that he was able to finish his career on a high note after what he went through and everything that he had to do”. (Fred Hoiberg - Nebraska Cornhuskers HC)

Overall

Rienk Mast has just finished his college career with the Nebraska Cornhuskers. His profile is that of a playmaking stretch big. Offensively, his main weapon is his perimeter shooting, which allows him to stretch the floor, but he is also effective in the low post. His remarkable court vision, which lets him function as an added playmaker, is what really draws attention.Defensively, he is a big man who compensates for his athletic and rim-protection shortcomings with physicality, intelligence, positioning, and vocal leadership to direct his teammates. For his future, he will need to be more consistently focused on defense and improve his lateral mobility. Although he possesses characteristics that attract NBA scouts, the most realistic path for the native of Groningen is to build a solid European career—perhaps starting back in the BNXT League and then climbing the levels.
