Jalen Brunson was absolutely fantastic against the Utah Jazz. He is currently leading the NBA in total points scored in the playoffs. He has done this while having only four turnovers in six games. To put that number of turnovers in perspective relative to his ball handling load, Dwight Powell has five turnovers despite playing less than half as many minutes and handling a miniscule ball handling load relative to Brunson. Luka Doncic has three times as many turnovers Brunson despite missing half the games in this series.
All of this success would appear to have answered any questions regarding how Brunson would deal with the length of playoff defenses.
