Even if Turner was in the same situation as Saladino, that's one guy out of, what, 10k that struggle after being awful for years?
I think you missed the point. I know he was hurt, but it's not like the injuries forced him to miss the whole year; he got in 281 PA's, and based on the prior years (although not as bad as 2017), he was very mediocre, in MILB and MLB. While the back injury forced him to go from mediocre to bad, he still wasn't anything special prior to.
