The purpose of my post was to suggest a way for two franchises in need of a change to make a swap of quality for quality (instead of dumping a Hall of Famer for bad-contract has-beens or never-weres)... and to replace Betts with another All-Star with roots in New England who may want to play in Boston and sign on in '21.
One blueprint for success is to try to lock up a solid core to build around that will keep your team in contention for years. Boston had that in 2017, with the thriller Bs, Devers, Vazquez, etc., but now that core may only be together for another year... if that.
If Mookie won't re-sign but the Sox can sign Springer for five years, then that's a good position player -- along with Devers and Bogey, at least -- that they don't have to worry about for awhile. Bloom in Boston shouldn't have to keep transitioning regulars or platoon guys on and off the roster every year like he did in Tampa. He needs and wants to focus on pitching.
What other available rightfielder would you prefer (I asked this in a thread a few weeks ago... and personally, I won't settle for any Pederson or Pollock)?
