That's my opinion for MVP. That award has the word "value" in it's title, so it's up for everybody to define what that value means and how to assess it, possibly beyond just "best player". I assign a higher value to production on a playoff contender over equal production on an also-ran. Cy Young I usually treat more as best pitcher. Maybe that's inconsistent, I don't know, just how I view the two awards.
I'm not really interested in getting into that debate. I think Hernandez has been slightly better this year at helping his team prevent runs. Maybe he's gotten more help from his defense than Kluber has gotten from his, I don't really see the need to separate that unless there is a major difference, which I don't think there really is here. In fact, depending on if you prefer FIP or xFIP, the independent stats each favor one of them, so again it's down to personal preference.
I think it's incredibly close and I don't think there is a right or wrong choice between the two.
