I see it more like this... The Sox had this hole and even with having every piece of statistical data on Yermin Mercedes, they still chose to play guys like AJ Reed and Matt Skole over him. The Sox know more than anyone in baseball about Yermin, and still went out and found waiver wire garbage to start over him. Even with the Sox decision making, no other team in baseball has been wiling to acquire Mercedes. The odds are really, really, really high that 2+2=4 here, and he joins the scrap heap of 4A players who never could break though after putting up insane minor league hitting numbers.
