Marcus Thornton

Marcus Alexander Thornton (born February 9, 1993) is an American professional basketball player. He was drafted by the Boston Celtics with the 45th overall pick in the 2015 NBA draft. Thornton completed his collegiate career at the College of William & Mary (W&M) in 2015 and was named the 2014–15 Colonial Athletic Association Player of the Year. Thornton spent 10 days on the NBA roster of the Cleveland Cavaliers, but never played.

On February 25, 2015, Thornton surpassed 2,052 career points to overtake Chet Giermak's long-standing school record. Giermak's mark stood for 65 years – the longest-lasting NCAA Division I school record in the nation at the time it was broken.

High school career Thornton, a native of Upper Marlboro, Maryland, fell in love with basketball at an early age and was considered very talented throughout his youth. He attended Bishop McNamara High School, a perennial basketball power, not because of the sport but because of its academic reputation and its proximity to his home. In his final game for Bishop McNamara, he scored a career high and school record 43 points. He averaged 11.1 points, scoring 355 on the year, and was named to the CAA All-Rookie Team. He increased his scoring to 18.8 points per game in 2012–13 while he began to establish himself as a player who could create his own shot late in a possession. The Tribe lost by one point to Delaware, 75 to 74, barely missing out on the program's first-ever NCAA tournament appearance. Thornton's potential game-winning jump shot rattled off the back of the rim as time expired.

Entering his senior season, Thornton was selected by the league's coaches as the preseason CAA Player of the Year. The school record had stood since 1950 and was the longest-standing Division I men's basketball school scoring record in the country. On March 5, Thornton was named as the 2015 CAA Player of the Year, becoming the first W&M player to win it in the 32-year history of the award. He also repeated as an All-CAA First Team selection, becoming just the second W&M player to earn the honor twice (joining Adam Hess in 2003 and 2004).

For the second consecutive season, William & Mary earned a berth in the CAA tournament championship game. However, for the first time in school history, the Tribe entered the tournament as the number one seed. They went on to lose the 2015 tournament's final game to Northeastern, 72 to 61, thus ending their chance at a bid into the NCAA tournament. Thornton, however, was named to the CAA All-Tournament Team as well as being the tournament's leading scorer in both 2014 and 2015. By owning the regular season tie-breakers over the other three co-champions, William & Mary earned the automatic National Invitation Tournament (NIT) bid, making the 2015 appearance their third in school history. On March 17, 2015, in the NIT's first round, Thornton scored a game-high 23 points despite the Tribe's 70–67 loss to Tulsa. Thornton finished his collegiate career having amassed 2,178 points, which is the most in William & Mary history and seventh most in CAA history as of the end of the 2014–15 season. He was the first W&M player since 1981 (Mike Strayhorn) to earn the distinction and only the sixth overall to that point. He later joined the Celtics for the 2015 NBA Summer League and averaged 5.1 points and 1.1 rebounds in eight games.

On November 1, he scored a season-high 29 points on 11-of-17 shooting in a loss to Melbourne United. He appeared in all 28 games for the last-placed Kings, averaging 12.8 points, 2.5 rebounds and 2.0 assists per game, but shot just 37.7 percent from the field and 28.1 percent on three-pointers.

Maine Red Claws (2016) On March 1, 2016, Thornton was acquired by the Maine Red Claws, the Celtics' D-League affiliate. Four days later, he made his debut for Maine in a 122–106 win over Raptors 905, recording seven points, one rebound, three assists and one steal in 15 minutes.
