I was thinking about this and it's not just about Wemby learning to pass off double teams, he can certainly improve but he knows how to do that already. He's also an above average passer which is logical given he can see the whole court at all times. No, what's keeping him from averaging more assists is simply that he doesn't touch the ball nearly enough.
I can see a future with him becoming a floor general ala Jokic or LeBron, where every single possession the ball passes through him, but he's not there yet.
He's still learning the NBA game and he's often waiting on the side for his teammates to even acknowledge him.
Eventually he'll become that, and I wouldn't be surprised for him to average 6 to 8 assists per game then, on top of everything else (which is mind blowing).
