That's not a good thing, BTW. He will be nuclear awesome until his arm explodes like a cheap party-favor.
Still, there is zero risk of losing all value. If he blows out his arm, he just turns into a nuclear DH. :)
But this speculation is, IMHO, reeeaaaaaaallly reaching. Two scouts go and try to figure out what Ohtani wants and come back with two completely contradictory answers. That means we know zero. My guess is that he wants a big market team that is NOT NYY/BOS/LAD...somewhere big, but not so big that he is blown away by all the attention and demands and cultural confusion. That isn't necessarily Seattle though. Could just as easily be the Nationals or Orioles, the Astros, the Rockies, Diamondbacks, Marlins, Braves, or Cardinals. And it's only a guess. There's a 90% chance I'm wrong.
