He was looking really good at the end of the season. If he can come into the season in that kind of shape, they might be really formidable. It's easy to forget how ludicrously dominant Zion is, because he's never in peak shape.
Their ceiling depends on what they can get for Ingram. I was just thinking about an Ingram for KAT trade. It makes positional sense for both teams and I don't like either player.
