From a 5-foot-2 freshman to the NBA's most improved player
In short: Imagine starting high school at 5 ft 2 in and ending it as a record-breaking scorer. CJ McCollum didn't just grow into his frame; he engineered a transformation that took him from an undersized underdog to a primary NBA playmaker and a labor leader for the league's elite.
CJ McCollum’s trajectory is a study in physical and technical evolution. As a freshman at GlenOak High School in 2005, he was considered considerably undersized at just 5 ft 2 in. By perfecting his shooting technique and experiencing late physical growth—adding four inches in his third year and five in his second—he reached 1,405 career points to become the school's highest scorer.
This momentum carried into his collegiate career at Lehigh University. In 2010, McCollum made history as the initial Patriot League athlete to win both Rookie and Player of the Year awards, despite weighing 165 lb and measuring 6 ft 3 in as a freshman. He was a prolific scorer, eventually becoming the league's all-time leading scorer with 2,361 points. He also added 30 pounds of muscle during his four years at Lehigh, choosing to stay for his final year to complete his degree in journalism despite being a projected top NBA draft pick.
McCollum’s NBA career is defined by his ability to adapt to shifting team dynamics. After being selected 10th overall in 2013, he spent years refining his role before a massive breakout in 2015–16. Following the departure of four key starters, he was elevated to a primary scoring role, averaging 20.8 points per game and earning NBA Most Improved Player honors. He championed the league's athletes as the National Basketball Players Association president between 2021 and 2025, exerting his impact outside of basketball.
His career is marked by high-pressure performances, including a 41-point playoff outing in 2017 and a franchise-record 28 points in a single first quarter in 2018. From his roots in Canton, Ohio, to the leadership of the NBPA, McCollum's path illustrates the power of deliberate development and physical transformation.
