That is how it works. Kim's oWAR is 4.4; Matt Olson's is 4.8 (I'm going off baseball-reference). In no world is Kim even close to as valuable as Olson offensively.I
That’s not how it works though.
You don’t just get a boost for playing 2B or SS or CF.
Those positions are valuable. It’s true. Because they tend to see the most opportunities. But you still have to be good.
There’s no one who is a bad centerfielder who suddenly becomes more valuable than a great 1B simply because they play CF.
Kevin Kiermaier might be the best defensive CF in baseball this season. Freddie Freeman is one of the worst this year.
Their WAR values aren’t anything close to one another.
