The thing to me is they had clear OF and bullpen and even 1b plans before the season. However, injuries, weak depth, and some players just flat out not producing made them all weaknesses. It’s not like any of them were ignored.
And when you have weaknesses like that, your only options are internal ones until other teams are willing to trade. To me, the Sox absolutely did not exhaust all internal options, but I am not going to pretend they didn’t try them…
