I’d say he has.
Adrian Wojnarowski of ESPN:
The 26-year-old Harris is a good 3-point shooter who works well off the ball and at least defends hard. He has also developed as a ball-handler, allowing him to expand his offensive responsibilities.
I’m a little surprised Brooklyn cut so deeply into its 2019 cap space for Harris. But the Nets will try to sell free agents on their culture, and Harris exemplifies all the positives of it. It’ll be nice to keep him around.
