Sure, position-less game. Simmons is in the dunker spot or a roll threat when playing with Dame. Or Dame can get off ball and let Simmons create like Draymond does for Curry. And Simmons initiates offense when Dame is off the floor. I think the fit is seamless. And I'd be all in on D'Antoni if we can get Ben because of his ability to maximize these two on O. I'd call Simmons a point-center.
Simmons can legitimately guard (as in LOCK DOWN) 1-4 on the defensive end.
Outside of maybe AD, I can't think of a better pairing for Dame. Been saying this since Ben came into the league.
