If Jacobs was the #11 prospect in Boston's system, that immediately makes him a top 10 prospect in our system. So on paper, it sems like a good return to me (for an aging lefty specialist that can't close).
However, in reading the brief scouting notes on Jacobs, what I got is: toolsy football player that can't hit. Just what we need more of in our system! Maybe the Sox think that if we acquire enough players of this profile, eventually one of them will turn into Carl Crawford.
All in all, not thrilled with Jacobs but can't really complain about what Hahn did here.
