He sucks at 2B, but when healthy, he's not really bad at 3B, at least over the last 3 years.
He's not someone I'd want as my FT 3B, and neither is LeMahieu.
I have faith in Devers. My hope is he can become close to average on defense within a year or two. If he hits like I think he will, I'm fine with a slight negative defense, but moving him to 1B may still end up being what is best.
He's still young enough to improve. I think he's got quick reflexes, which helps at 3B. His range is already +3.7 on fangraphs, but he makes bad throws too often. That's something that is easier to correct than range, where you either have it or you don't.
We'll know more after this year. We'll also know more about Dalbec & Chavis.
