Yes, the lack of turnovers was huge. It shows he's learning the NBA game. Earlier in the season he was consistently taking the ball into the paint and picking up his dribble without having a shot or a pass, resulting in a turnover. I'm not seeing that anymore.
He also hit two huge shots in crunch time; the floater in the lane after the pump fake with the clock expiring and the layup that Bam got called for goaltending. Very good shot selection. He ran the offense and distributed the ball, but knew when to take the shot himself and converted them.
I think he was helped on defense by not having to defend any big guards. They had him on Nunn and Dragic. Fortunately, Ben Simmons is out tonight but the Sixers still have Milton, Burks, and Korkmaz - all in the 6'5" to 6'7" range. I will be looking to see if he gets pushed around.
