Can we do worse? Imagine telling Zuttah to be a power center and have to take an opposing NT to school. In ZBS that fits Zuttah, he just has to block a zone, maintain the block, and block onto the 2nd level. Something I actually think Zuttah is solid in, however when asked to handle 1v1 blocking assignments, push back NTs/DTs then he struggles. I think the adjustment to the cut-block rules also affected him plenty because that's an area that doesn't really rely strongly on strength. If the Ravens desire to add more power/gap is a concern because Centers have the toughest job there, he's going to be asked to hold back-side A gap and back-side B gap.
I think we can do worse, but we might even do better if we bring an average C who can play with the type of strength that Zuttah doesn't bring to the table.
