Just having his ball-handling available would be invaluable to this team. Even if he isn't "playing PG", per se, I'd be so bold as to say that he's immediately our 2nd best ball-handler the second he steps on campus.
And I still stand by my previous belief that unless Barnes pulls a PG from the portal, which is always very possible, then Dilione is going to play there quite a bit, next year. Getting this headstart only further solidifies that belief. Truthfully, the way he plays reminds me a lot of Zakai Zeigler if ZZ was 7" taller.
