What kind of fWAR do you think he's going to put up over the next few seasons? I mean, as much as it pains me to admit it, it's hard to really disagree. Outside of the top defenders/prime defensive spots, it's probably foolish to rely on positive defensive value, especially for someone with his clear limitations. He's made plenty of strides in the area, but he's never going to be fast and he's going to get turned around 4-5 times a year. That being said, from what I can tell, the only real difference offensively being 2018 and 2019 is that he's down 25 points in BABIP. Walk rate is down 1%, K rate barely up, and his batted ball profile shows a few more line drives, a few more hard hit balls, and significantly less soft hit balls (10.9% to 16.8%). Basically I don't think he's too far off from that 115 wRC. Whether a 115 with slightly negative defensive value is enough is a different question, but I think he's still an above average hitter.
