There's a lot of noise at the team level for DRS, so it's not accurate to say, "x player plays on crappy defensive team y, therefore he might be good on good defensive team z." Looking at Daniel Murphy, for example, the Cubs had the 6th best team DRS in 2018, yet he was terrible for them. They were a better team by DRS than the Dodgers, who "fixed" Machado. DRS doesn't have a ton of correlation year to year either, for whatever reason. Arizona was +118 this year, +13 last year. Milwaukee was +91 this year, +23 last year. Boston was -44 this year, +71 last year. So if players tend to be crappy over time, which is why I used 3-year data, that tells me that lo, they may be crappy regardless of what team they're playing on. As always, when painting with broad strokes it's important to look at finer detail (Machado did get better and the Mets have been poorly rated by DRS in '17/18), but dismissing its usefulness for individual players due to current year data is not wise, IMO. I do find DRS to be the most thoughtful indicator of defense publically available, followed by FRAA and then UZR as a distant third. I'm looking forward to MLB providing more Statcast data with regard to defense as they've provided peaks into some really exciting defensive tools. As for Cabrera specifically, he has a negative value for his career defensively via Fangraphs. As shown, DRS has him as a bad defender and FRAA backs that up. And from what limited amount I've seen of his play, specifically at shortstop, I'd tend to think his lack of mobility and declining arm strength would be hinderances regardless of what team he plays on.
