Knecht was selected with the 17th overall pick by the
Los Angeles Lakers in the
2024 NBA draft and he signed with them on July 3, 2024. Knecht made his NBA debut on October 22, 2024, in a 110–103 win over the
Minnesota Timberwolves, scoring 5 points. On November 13, Knecht scored a then career-high 19 points on 7-of-8 shooting from the field with 5-of-5 shooting from three-point range in a 128–123 win over the
Memphis Grizzlies. Three days later, he broke this record, scoring a then career-high 27 points along with seven rebounds, two assists, and two steals in a 104–99 win over the
New Orleans Pelicans. On November 19, Knecht scored a career-high 37 points, including nine three-pointers, in a 124–118 victory against the
Utah Jazz. He also tied the record for the most three-pointers made in a single game by a rookie in NBA history. On February 6, 2025, the Lakers agreed to trade Knecht,
Cam Reddish, a future first-round pick, and a pick swap to the
Charlotte Hornets in exchange for
Mark Williams. However, the trade was rescinded two days later after Williams failed his physical with the Lakers. Returning to the Lakers, for the rest of February, he scored 5.1 points per game and shot 32.1% on three-point shots. However, during March and April, he increased his scoring average to 9.7 point per game and 43.3% in three-point shots. During that stretch, he had games of 32 points against
Denver and 27 points against
Portland. ==Career statistics==
