He went on to appear regularly for the Blue Devils, contributing as a defensive anchor in the paint while continuing to develop his offensive game.
As a freshman, Lively averaged 5.2 points, 5.4 rebounds, and 2.4 blocks per game. His defensive impact earned him spots on both the ACC All-Freshman Team and the ACC All-Defensive Team. On April 4, 2023, Lively declared for the 2023 NBA draft, forgoing his remaining college eligibility and beginning his professional career.
NBA Breakthrough (2023-2024)
The Oklahoma City Thunder selected Lively 12th overall in the 2023 NBA draft and immediately traded him to the Dallas Mavericks, where he signed his rookie contract on July 8, 2023. He made his NBA regular-season debut on October 25, 2023, posting 16 points, 10 rebounds, one block, and one steal in a 126-119 win over the San Antonio Spurs. The performance offered an early glimpse of his two-way potential at the professional level.
Lively finished his rookie season as one of the most talked-about young centers in the league, earning selection to the NBA All-Rookie Second Team. He capped the campaign by helping the Mavericks reach the 2024 NBA Finals, where they ultimately fell to the Boston Celtics in five games. The playoff run, which included appearances on basketball’s biggest stage, cemented Lively’s reputation as a foundational piece for Dallas.
Dallas Mavericks Era (2023-Present)
Lively joined the Dallas Mavericks in 2023 and quickly became a key frontcourt contributor. In his rookie year he earned NBA All-Rookie Second Team honors while serving as a rim protector and lob threat alongside Dallas’s core. His length, mobility, and finishing around the rim made him a natural fit for the Mavericks’ offense.
To begin the 2024-25 Dallas Mavericks season, Lively played in 32 games with 25 starts, averaging 9.1 points, 7.8 rebounds, and 2.6 assists. On January 22, 2025, Lively was ruled out for two to three months after suffering a stress fracture in his right ankle. He returned to action later in the calendar year, but on December 10 he suffered another major injury setback, undergoing a season-ending procedure on his right foot to address lingering discomfort.
Driving Style and Strengths
Lively is widely regarded as a mobile, defense-first center whose shot-blocking, rebounding, and ability to switch onto smaller players on the perimeter set him apart. He excels as a vertical spacer in the pick-and-roll, finishing lobs at a high rate while also protecting the rim on the other end. His combination of size, instincts, and athleticism makes him a long-term defensive anchor for Dallas.
Notable Events and Milestones
Among the most memorable moments of Lively’s early career is his NBA debut, when he recorded a 16-point, 10-rebound double-double against the San Antonio Spurs. He also reached the 2024 NBA Finals as a rookie, an achievement few first-year players experience. His selection 12th overall in the 2023 NBA draft and his immediate All-Rookie recognition mark him as a significant piece of the Mavericks’ young core.

2025 Season Performance

On January 22, 2025, he was ruled out for two to three months after suffering a stress fracture in his right ankle, a significant absence for the Mavericks’ frontcourt rotation.
Lively eventually returned from the ankle issue, but on December 10 he suffered another major injury setback, undergoing a season-ending procedure on his right foot to address lingering discomfort.

His development as a two-way center, combined with the lessons learned from a 2024 NBA Finals run, leaves Dallas optimistic about his future impact once he returns to full health.
