I think of that group Mitchell has made the biggest stride as a playmaker actually, he's consistently made reads in the PNR/out of double teams in this series I didn't think he was capable of (seriously, did you see him just relocate out of the double and throw that cross court skip pass for the corner 3 last quarter? Dude is evolving
). And you probably didn't mean this but I don't think Zion's a poor decision maker. Honestly if his handle didn't regress from college to this season like it did and he was given the keys to the offense people would be shocked at how good of a passer he is. Probably the best decision maker of the group tbh.
