While I am not really thrilled with it, in truth especially in the AL, they have moved more toward where the Sox have always been regarding the SS position. However now that pitching is beginning to once again exert its dominance more like it was in the 60's through 80's, we will very likely see more defensive minded SS's even in the AL. I don't expect that to change the Sox though. Their thinking in this regard spans decades, maybe even centuries. As long as Fenway stands, they will always prefer no glove, all hit SS's. Look at the current apple of their eye, XB for example.
They have probably buried the scout that brought Iggy into the organization somewhere behind the scoreboard sweeping up after the game is over.
