I think itd be all bias if i just stood back "Ah RIZZOS DA BEST PLAYER" but i linked his fangraphs page, stated how he deserves a better rating.
And if you're worried about his defense, i believe his numbers last year had him a terrfic first baseman..... Its not just offense (:
And about the previous year thing, i dont think it matters much as they have Corey Kluber incredibly high (which he should be, he was freaking awesome lol)
