This group is -12 offensively, and considering they’re mostly above average defenders, we might have our first deviation from the norm. With a +2.5 position adjustment for CF, these guys would have to be something like -10 defenders in center field to be two wins below average. But there’s no way to make that argument - Patterson, Abercrombie, Duffy, Ellison - these guys are good defenders.
So, teams apparently value center fielders if they can hit well. But as soon as a CF, even as a plus defender, shows that he’s not a great hitter, he gets discarded.
It’s interesting, however, that we didn’t see this at SS or 2B. There’s not a glut of premium defensive middle infielders available for nothing. So, defense up the middle is valued a lot more for IF than OF? Sounds plausible."
