My guess is, if you polled fans or baseball writers, you find a wide gap in opinions on where Bogey ranks on defense.
My guess is you;d find a wider gap that 19th vs 30th out of 30.
It does concern me that the gap between 19th and 30th is so wide, but that does not mean I'll throw both metrics out the window. They both are probably more objective and fair than my own observations. I've played baseball a lot in my life. I've watched thousands of games, of which over 95% involved a Sox game. I love defense and pay particular attention to it, especially SS defense. Does that make me an "expert?" Probably not, but I do think I have a pretty good idea about what tremendous defense is at SS, what is average, and what is below average or awful (by ML standards).
Personally,, I'd guess Bogey is somewhere between 22nd and 28th on defense, but I really have no way of knowing, since I barely watch more than 3 games by some SSs per year. I feel pretty certain, he's between 19th and 30th as the two metrics place him. Probably UZR/150 ranks him higher than he belongs and DRS lower than he belongs. Perhaps one is way off. I seriously doubt both have him off to the point where he is really ranked 13th to 17th or "average".
