When Jaylen Brown entered the NBA in 2016 he had all the athleticism, but was still rather raw. As a rookie, Brad Stevens still gave the #3 overall pick solid playing time on an Eastern Conference contender. I remember Jaylen turning down an All-Star weekend slam dunk challenge invite, because he said he'd rather spend the time working on his game and not be distracted. And work on his game he has. Brown came into the league needing to sharpen up his handles and as you can see by this video released by the NBA this weekend what was once a weakness is now a strength.
