I think EMJ can produce consistent exit velocities and swing decisions. But his style of hitting isn't really that of a slugger. His style is more of that of a well-rounded hitter. Because of this, I'm more optimistic of his skills translating to MLB than I would a hitter like Wilken, who is more of a 3TO kind of guy. As my previous posts suggest, I feel like the league has largely learned to combat those kinds of hitters.
As far as the Brewers offense goes, the proof is in the pudding. If Ortiz was batting .230, and our platoon/bench players were simply below average, rather than abysmal, I think most of us would feel more comfortable.
I'm not arguing that the current state of the team is playoff-worthy. It isn't, and it hasn't been acceptable. With that said, it's early. The Cubs losing Steele and Shota to injury have opened a door to them cooling off. In another month, perhaps the Brewers' pitching stabilizes and the infielders warm up, along with Yelich. Lots of season left before decisions need to be made, IMO, but if the current team continues to scuffle, everything is on the table.
