And since peak Trout was, like, 2013 and he's not even twenty-five then I don't really think it's that simple.

Though if Trout's aged out of his elite centerfield defense (which is possible - that's kind of a young man's thing) and this is more of a bat-to-bat comparison then you may end up being right.

Durability could come into play too. Last year was Harper's first healthy year. It can be true that he's actually that good but still not capable of staying healthy and productive for 150+ games annually. Eric Davis only spent a couple years being as good as he actually was too.
