Cason Wallace’s Father: Mike Wallace

Mike grew up in East Texas before establishing his family in the Dallas area. Alongside his professional work as a barber, he became involved in youth basketball coaching and community sports programs.

His experience working with young basketball players gave him valuable knowledge about the importance of fundamentals, discipline, and regular practice.

During their childhood, Mike encouraged Cason and Keaton to compete against each other while maintaining a strong relationship as brothers.

According to a 2024 interview published by The Oklahoman, the Wallace brothers regularly played basketball in the driveway of their family home, sometimes continuing until one or two o’clock in the morning.

Their intense games occasionally attracted complaints from neighbors because of the noise.

Mike remembered that Keaton focused heavily on scoring, while Cason was particularly interested in defense. Their different playing styles created a competitive environment that helped both improve.

Rather than discouraging their rivalry, Mike encouraged them to use competition as motivation while continuing to support one another.

His guidance helped Cason become an outstanding perimeter defender, a skill that later established him as a valuable player for the Oklahoma City Thunder.

In October 2024, Mike attended a Thunder game against the Atlanta Hawks in which both of his sons played against each other in the NBA for the first time.

For Mike, seeing both children reach professional basketball represented the fulfillment of a family ambition that had developed over many years.

During interviews following the game, he expressed pride in the brothers’ achievements and emphasized the importance of their close relationship.

Kimberly raised Cason and Keaton alongside her husband, Mike, in Dallas, Texas.

Although she generally maintains a relatively private life, Kimberly has appeared in interviews discussing her sons’ development and their relationship with each other.

She has consistently emphasized humility, gratitude, and the importance of family relationships.

During an October 2024 interview with The Oklahoman, Kimberly expressed pride in seeing Cason and Keaton compete against each other at the professional level.

She described both sons as humble individuals who remained grounded despite reaching the NBA.

Cason Wallace’s Siblings: Meet His Older Brother Keaton Wallace

Cason Wallace has one publicly documented sibling, an older brother named Keaton Wallace, who is also a professional basketball player.

Keaton has been one of the most influential people in Cason’s life, serving as a role model, training partner, and source of motivation throughout his basketball journey.

Keaton Wallace – Cason Wallace’s Older Brother

Keaton Wallace was born on February 26, 1999, in Richardson, Texas, making him approximately five years older than Cason.

Like his younger brother, Keaton developed a passion for basketball while growing up in the Dallas area.

He attended Richardson High School, where he became a standout basketball player and earned recognition for his scoring ability.

During his senior season, Keaton averaged approximately 22.2 points, 4.6 assists, and 3.9 rebounds per game, earning District 9-6A Offensive Player of the Year honors.

After graduating from high school, he attended the University of Texas at San Antonio (UTSA), where he played college basketball for the Roadrunners from 2017 to 2021.

Keaton developed into one of the university’s most productive players, finishing his collegiate career with 2,080 points.

According to his official NBA biography, he became the second player in UTSA history to surpass 2,000 career points.

He also earned three All-Conference USA Second Team selections during his four seasons with the Roadrunners.

Despite his impressive college basketball career, Keaton was not selected in the 2021 NBA Draft.

He subsequently began his professional journey in the NBA G League, playing for organizations connected to the Los Angeles Clippers and Atlanta Hawks.

Keaton signed a two-way contract with the Atlanta Hawks in July 2024, allowing him to pursue an NBA career while continuing his development.

His persistence eventually gave him the opportunity to face his younger brother in an NBA game.

How Keaton Wallace Influenced Cason’s Basketball Career

Keaton Wallace has had an enormous influence on his younger brother’s approach to basketball.

As children, the brothers regularly competed in one-on-one games in their backyard in Hamilton Park.

Because Keaton was older and more physically developed, Cason frequently faced a difficult challenge when attempting to score against him.

These competitions encouraged Cason to develop his defensive instincts and learn how to compete against stronger opponents.

Keaton also encouraged his younger brother to remain disciplined in school and dedicate additional time to basketball training.

In his official University of Kentucky biography, Cason identified Keaton as the greatest influence in his life.

Speaking about his brother in October 2024, Cason acknowledged that Keaton’s work ethic had helped shape his own approach to basketball.

He explained that Keaton frequently encouraged him to practice harder and remain committed even when he felt tired or lacked motivation.

The two brothers eventually reached the NBA through different paths.

Cason became a first-round draft selection in 2023, while Keaton spent several years developing through the G League before receiving opportunities with Atlanta.

Despite their different journeys, their relationship remained close.

When Did Cason Wallace Play Against His Brother Keaton?

One of the most memorable moments in the Wallace family’s basketball history occurred on October 27, 2024.

On that day, Cason Wallace and Keaton Wallace faced each other in a regular-season NBA game between the Oklahoma City Thunder and Atlanta Hawks at Paycom Center.

The Thunder defeated the Hawks 128–104, but the result was not the only reason the game was special for the Wallace family.

The brothers shared the court for approximately 70 seconds during the closing stages of the game.

Their parents, Mike and Kimberly, watched from the stands alongside other family members.

After the game, both brothers discussed how meaningful the moment had been after years of practicing together as children.

Cason described the experience as a special moment for the entire family, while Keaton acknowledged that playing against his younger brother fulfilled a dream they had shared growing up.

The brothers also exchanged jerseys during their preseason meeting earlier that month, creating another memorable family keepsake.

In 2025, Cason and Keaton returned to Richardson High School during the offseason to practice with the school’s basketball team, continuing their connection with the community where they developed their skills.

In his only college season, he averaged 11.7 points, 4.3 assists, 3.7 rebounds, and 2.0 steals per game.

His defensive performances and basketball intelligence attracted the attention of NBA scouts, leading him to declare for the 2023 NBA Draft.

His family celebrated the achievement together, recognizing the years of training and sacrifice that had helped him reach professional basketball.

Wallace also used his draft-night clothing to acknowledge his childhood neighborhood, wearing a suit featuring the letters “HPT,” a reference to Hamilton Park, Texas.

He explained that the tribute was intended to encourage young people from his community to believe they could achieve their ambitions regardless of their backgrounds.

After joining Oklahoma City, Wallace quickly became known for his defensive versatility, perimeter pressure, and ability to contribute without dominating the basketball.

He earned NBA All-Rookie Second Team honors following the 2023–24 season and helped the Thunder win the 2025 NBA championship.
