If COL moves Arenado before spring training, there aren't many possible destinations given the young talent needed for COL to sell it to their fans plus the ability to take on his big deal plus COL's wanting to get him out of the the division if not the league (ruling out the Dodgers). I think the three main bidders would be/are STL, TEX, and NYY. I'm not sure how much money STL can take on and TEX doesn't have a lot of young talent to move, so I could see the match with the Yankees, who have a pretty good replacement to return as part of the package in Urshela, six months younger than Arenado, still pre-arb, and a 3.4 bWAR last year.
