Since punting 2 years of World Series goodwill is desirable. They still have business to attend to this year - the season has been rough, but the AL has been mediocre outside of 2 teams. I think if this is a 90 loss team you will see some substantial changes and veteran signs. When you gouge your fanbase like the Sox do - it is the least you can do. Prospects will be added smartly - like they have this season. The story of their season is about basically 15 wins of production being (Ellsbury, Victorino, Salty) being replaced by bubkus (Bradley, Pierzynski, misc chum in RF).
I think promoting Vasquez to start makes sense - he might be worse than AJ offensively but he at least provides a dimension at a serious restaurant quality level. Betts has so much promise that he could help with the outfield thing. The run prevention has largely been good - the question is whether you think they can realistically catch the teams in front of them. The East is a crapshoot - and so there is some merit in continuing to chase.
