Granted your starting center fielder doesn't count as depth at centerfield. However, depth can be a starter at some other position provided you have depth at that position. Eaton can play center. Could Soto play right? If so then you just need depth in left, and there's Matt Adams. In that case, we don't need anything beyond Robles and Eaton for centerfield. Surely not Stevenson. Hell, we don't really need Taylor.
