I think we have gotten spoiled by what Albies and Acuna did at very young ages. Not every good prospect is an uber prodigy like those two. Cruz is young enough that he could re-establish himself as a good but not elite prospect.
I know he has time. Again, I'm not trying to render a verdict on him. I'm just saying that even at 17-18, OPS'ing under .500 is a lot different than something like .675. There is not great, then there is flat out awful. Cruz has been flat out awful.
Not giving up on him, just recognizing his performance so far for what it is. Not a good sign.
