Kevin Knox was labeled one of the NBA’s “worst” players in 2018-19. That may have some validity, but the context matters. He was asked to do a lot as a 19-year-old, averaging the most minutes on the New York Knicks, which became too much in his first year. This explains the awful efficiency numbers.
Something that is a little more difficult to defend is his defense. He did not have good defenders around him for the most part, but at times Knox looked lost, or he wasn’t trying. His rebounding has to improve for a player his size.
