I don't know if you are referring to me but that is something I have said and will say again. It was and remains true. It just happens that its the one tool that can stand on its own and is a very good one. Is it generational? Doubtful. He will have to make a dramatic improvement in his health and stamina to maintain anything close to this pace. Remember being concerned about his legs holding up? At this point last year he was hitting .362 with an .899 OPS and fell off a relative cliff after. He didn't run away with the batting title, the season just ended before he could be caught. The pure hitter flopped badly in the second half, improbable as it may be. He's not Rod Carew, and as you state, the Twins knew what they were giving up, that goes both ways.
Where would he play? We already have enough stone handed fielders to find spots for. The FO knew the DH was occupied. There have been volumes on these pages about a roster crunch. Yes, I know he would have a spot hitting like this but who loses out? Yes, the roster looks much different without this trade, someone else would have gone somewhere, but it doesn't change that he doesn't project to be anything more than a powerless DH defensively.
Making proclamations about this trade less than 80 games in is shortsighted at best. Writing these pieces in the name of content production is the worst thing about the internet. While this is a SI article, Twins Daily could take the lesson as well. Less but better content. There is nothing to talk about here.
