I like your enthusiasm, but 30 minutes all season basically makes him a starter.
JJ is hurt for a while, so Kiyan will get extra minutes for at least the next couple weeks.
There is only 80 minutes in the backcourt. Kiyan is not really a SF, not defensively.
George has to play a lot - 30 minutes. Sure, Kiyan can take a few of those remaining 10 minutes at PG, but so will Fennell and maybe JJ and maybe Zephir.
At the 2G, we have JJ, Kingz and Kiyan, so, 30 minutes of those 40 are spoken for
Kingz can play a little SF, but looks a lot more like a guard, to me.
Betsey is bigger than Kiyan at SF, and you're going to have Donnie rotating into that spot, too.
If Kiyan gets 20 minutes per game once everybody is back healthy, that sounds pretty good to me. Don't ask too much of the young man. Let him blossom next year.
Dion Waiters only played 16 minutes a game as a freshman, and 24 minutes a game as a sophomore before he went pro.
