When Zion is out, Jerami can replace his minutes. When Zion is active, Jerami can play the backup minutes for both Ingram and JV in addition to Zion's backup minutes. Jerami can sweep the floor with second units, but he's not a better player than Ingram nor a better center than JV, so he wouldn't start if it were up to me. I have an inkling to play him at SG but if he plays significant minutes there then he can't play all of the backup 4 and 5 minutes plus some backup 3 minutes.
