The Dallas Mavericks drafted Jalen Brunson in 2018. It was the same night that they traded up for Luka Doncic. Brunson moved into that backup point guard role long held by J.J. Barea this season. Playing behind Luka caused his minutes to dip, though.
Brunson can absolutely ball. Look at his numbers as a starter. He averages 12.1 points, 5.1 assists, and 3.3 rebounds in 26.3 minutes per game over his 16 starts this season. Brunson produced 15.0 points and 7.3 assists a night in the eight times he played over 30 minutes.
