I think it just depends on cost and the availability of other 3rd basemen. If Andujar was available for good value and we were confident in his health, I think it would be kinda silly to turn down a trade for a cheap, controllable 3 win 3rd baseman just because he's a really bad defender. If we were confident in his ability to put up an .850-.900 OPS, I'd be willing to take the hit on defense. Especially if we weren't confident in getting anyone else to fill in at 3rd base this offseason. I would take Andujar and his defense over what we currently have any day of the week.
But there are more preferable targets out there and I would exhaust most of them before trying to target Andujar. If it did come down to that, though, he could eventually represent Freddie's replacement at 1st base if and when Freddie hits free agency in 2021.
