I would guess that the assumption would be that the sox would have gone out and gotten a true #1 starter in that time without giving up Hanley. That being said, I disagree with Gom's assumption.
Also, it is kinda painful to think about that farm system prior to the Beckett deal.
Lester, Buchholz, Sanchez, Bowden as starters. Papelbon, Delcarmen in the bullpen. Youkilis, Pedroia, Hanley in the IF, Ellsbury and Murphy in the OF. That was a pretty strong farm. Recent trades and callups have drained that resource for now.
