To me, the problem isn't that it's a lineup of kids. If they just went that route and put the kids in the spots they were supposed to be and ran with it, the team would be more enjoyable. However, over and over again, they just half ass it. Mayer will most likely go to 2b instead of SS. Anthony won't be designated a fulltime OF spot. Rafaela should just be the CFer 150 games a year. Force Abreu to face LHP and see if he gets better rather than in a parttime role. Give Fitts and Harrison starting rotation spots for the rest of the season. I don't know how they serve both masters of "remain in contention" and "play the kids."
I think they should actively be trying to deal: Chapman, Story, Buehler, Masa, Bernardino, Wilson, Romy, Toro, Hamilton, Duran, Wong, Refsnyder. These guys aren't going to be part of the next great Red Sox team. I think they hold onto Bregman as the "glue guy" and an additional bench coach for Cora. Maybe they work on a short term extension for him at big $$$.
