I'm expecting to lose both. On the bright side, Benitendi or Betts can move into center field, and maybe my personal favorite Bryce Bentz can take an outfield corner. His last name still starts with 'B' so he qualifies right? I think losing Bogaerts will hurt more; obviously we can fill the position (Lin, Iglesias) but the drop in offense will be noticeable. I'm also expecting to lose Sale.
But hey, let's enjoy 2019 and not worry about 2020 yet. We're going to be awesome this year. Since the Yankees will be better, the Sox will have to maintain a high level all season and thus will break 110 wins :)
