Assuming he's back and productive for the ACC and NCAA tournaments, I think NPOY for Zion is very likely.
ACC POY is a trickier case. My understanding is that voters aren't required to focus primarily on conference games, but in practice heavily weight them. Missing effectively 5.5-6.5 games (depending on tonight) is a lot of the conference season. That said, there's a couple of points will work in his favor. First, his pre-injury performance in ACC games was way beyond normal POY standards. Second, I think there are three players (Barrett, Hunter, and Johnson) who would carve up the voters who are reluctant to vote for someone who missed so much time. So my money would be on Zion for that one too.
