Dereck Lively II Bio
Dereck Jerome Lively II (born February 12, 2004) is an American professional basketball player for the Dallas Mavericks of the National Basketball Association (NBA). Standing 7 feet 1 inch tall, he plays as a center and is widely regarded as one of the most promising young rim protectors in the league. Lively played college basketball for the Duke Blue Devils before being selected 12th overall in the 2023 NBA draft. He is the son of a former Penn State basketball standout and a Philadelphia-based chef, a family background that helped shape his early path in the sport.
Early Life and Background
Dereck Jerome Lively II was born on February 12, 2004, in Philadelphia, Pennsylvania. He is the son of Dereck Lively, a Philadelphia-born chef, and Kathy Phillips Drysdale, a Southfield, Michigan native and former Penn State women’s basketball star. Drysdale held the Penn State record for consecutive field goals made and ranked in the top 20 in program history in rebounds and blocks. After her playing career, she worked for the Philadelphia 76ers in their entertainment division and later served as the Penn State women’s basketball marketing manager. Lively’s father battled drug addiction for years and passed away in 2012 from an overdose, and his mother passed away in 2024 after a battle with Hodgkin’s Lymphoma.
Growing up in Philadelphia, Lively was surrounded by basketball culture and family connections to the game. His mother’s professional basketball background gave him early insight into the demands of the sport, while the city’s deep hoops tradition helped fuel his development. By the time he reached high school, Lively had grown into a highly recruited prospect with rare physical tools for a player his age.
Path to Basketball
Lively attended Westtown School in West Chester, Pennsylvania, where he developed into one of the most dominant interior players in the country. During his senior season, he led Westtown to a 31-7 record and the Pennsylvania Independent Schools Athletic Association state championship, a run that included a victory over Perkiomen School, which was led by Ryan Dunn and Xaivian Lee. That season, he averaged 14.0 points, 14.0 rebounds, and 4.5 blocks per game, numbers that highlighted his two-way impact on the floor.
His high school play earned him a selection to the 2022 McDonald’s All-American Boys Game, along with recognition as Mr. Pennsylvania Basketball and the Morgan Wootten National Player of the Year. Rated as a consensus five-star recruit and one of the top players in the 2022 class, Lively committed to Duke on September 20, 2021, choosing the Blue Devils over scholarship offers from Kentucky, Michigan, and Penn State. His decision to play at Duke set the stage for a brief but productive college career.

Early Career (2022-2023)
Before the start of the 2022-23 college season, Lively was named to both the Naismith Trophy and the Kareem Abdul-Jabbar Award preseason watchlists, underscoring his standing as a top incoming freshman. As a freshman at Duke, he quickly established himself as a defensive anchor, averaging 5.2 points, 5.4 rebounds, and 2.4 blocks per game.

Following the season, on April 4, 2023, he declared for the 2023 NBA draft, forgoing his remaining college eligibility. His decision allowed him to begin his professional career at a time when his stock as a defensive specialist was steadily rising.
Dallas Mavericks Debut and Rookie Season (2023-2024)
The Oklahoma City Thunder selected Lively 12th overall in the 2023 NBA draft before trading him to the Dallas Mavericks. He signed his rookie contract with the Mavericks on July 8, 2023, officially beginning his professional career. Less than three months later, on October 25, 2023, Lively made his NBA regular-season debut in impressive fashion, recording 16 points, 10 rebounds, one block, and one steal in a 126-119 win against the San Antonio Spurs. The performance was an early sign of the immediate impact he would have in the league.
Lively’s rookie season earned him a selection to the NBA All-Rookie Second Team, validating his status as one of the top first-year players in the league. The Mavericks’ run through the 2024 playoffs carried him all the way to the 2024 NBA Finals, where Dallas ultimately fell to the Boston Celtics in five games. That postseason stretch, paired with his regular-season production, gave Lively valuable experience on one of the league’s biggest stages.
Dallas Mavericks Continued Role (2024-2025)
Lively began the 2024-25 Dallas Mavericks season in a starting role, playing in 32 games with 25 starts while averaging 9.1 points, 7.8 rebounds, and 2.6 assists.

The early portion of the season showed growth in his playmaking and scoring efficiency around the basket.
On January 22, 2025, Lively was ruled out for two to three months after suffering a stress fracture in his right ankle, a significant setback that interrupted his momentum. Later, in December 2025, Lively faced another major injury challenge when he was ruled out for the remainder of the season after needing a procedure on his right foot to address lingering discomfort. The back-to-back injuries tested his resilience, but his work in the early part of the season had already reinforced his importance to the team’s long-term plans.
