Those who have pointed out in this thread that my opening question is almost impossible to consider without factoring in what comes next are right, as far as I'm concerned.
I had not thought that part through all the way when I posted. Like for some others, losing home grown talents like these two, after seeing Betts go, would be a terrible gut punch for me, regardless of what comes next. But it's also true that if the Sox somehow bounced back quickly and became a serious contender, that it would soften the blow tremendously and bring me back, to whatever extent that was necessary.
I think that my unstated and not fully considered premise is that the Sox being a real contender will not happen if they suffer Bogaerts and Devers leaving.
And if it gets tested, I hope that premise is flat wrong.
