I guess it may be semantics to decide on the definition of 'productive MLB player,' but he's been above replacement level every year (yes, including 2018) other than his partial first-year of 2016. When you perform better throughout almost your entire career than the guys you can plug in at the position each offseason, I DO think that's a productive MLB player.... Above replacement level is a pretty low bar to set and he was -0.4 last year so he wasn't above replacement level either. He's at 0.9 WAR in 1,450 plate appearances in his career which isn't that much better than replacement level.
