#2 Lonnie Walker IV
After suffering a right medial meniscus tear in October of 2018 (for the second time in under two years), Walker missed considerable time with the Spurs in the beginning of the season. He ended up playing 17 games with the team coming off the bench to average just 2.6 points per game.
During his time in the G league, he didn't stand out with his unimpressive 1.5 turnovers to 1.8 assists per game. His efficiency in the paint was a huge concern with conversions like 54% from inside the restricted area and 39% from the non-restricted area inside the paint, which are fairly low by NBA standards.
His inability to finish at the rim and a high affinity to take shots from the midrange undermine his athleticism and defense in today's NBA. Clearly, he needs to work on his body control and his ability to finish in traffic as well.
