Problem, shmoblem. No one, including me, is arguing the defense is good or even adequate this year. It might even be the worst Sox defense in 120 years.
What your whining continues to ignore is that defense is not, repeat not, the sum of this team--not this year and not historically.
Please take a quick look at the Sox won-lost record and you will be astounded to discover they have a winning record and in fact are very much in the hunt for the wild card game and exceeding our expectations from way back in April.
Why is this so? Well, one reason is that those low-down, rotten, terrible fielders also come to bat now and then, and this team actually hits the ball pretty well and even scores some runs. Moreover, despite the porous defense that doesn't catch much or throw very well, the Sox rotation and bullpen now and then keep opposing teams from scoring as many runs in a given game as the Sox score.
During the John Henry era, the most successful in Sox history, the FO has gone out of its way to acquire hitters over fielders.
