Damyean Dotson was drafted by the New York Knicks in the second round of the 2017 NBA Draft. Dotson split his rookie season between the Knicks and the G League Westchester Knicks. The rookie guard made his NBA debut Opening Night during a loss to the Thunder. Dotson would go on to appear in 17 of New York's first 25 games, while also joining Westchester for four November contests. On Nov. 28, while with Westchester, the guard posted 23 points, a trio of three-pointers and three rebounds in a loss versus Maine. He then spent most of December with New York.

On Jan. 17, Dotson scored a G League career-high 27 points to go with nine rebounds in a win over Long Island. Dotson played in 22 of New York's last 28 games. On Apr. 6, Dotson scored a career-high 30 points and grabbed 11 rebounds in a home win over the Heat. It was his second double-double of the season.
