It's hard to judge Getz' performance re development simply because the inputs have been objectively weak.
The international signing classes were consistently at the bottom; now the rankings aren't perfect, but I'd liken them to college recruiting classes: if you are recruiting 2 star players, you aren't going to beat Ohio State.
And then there is the draft. I believe that Shirley is good evaluator of talent. But is he that good? - better than basically everyone else? Well, that's what he needs to be because the Sox punt away a lot of the picks in rounds 6-10.. But in doing that, the Sox are reaching for most of their 2-5 picks. If a guy is a consensus #50 and the Sox draft him at #50, if they pay him overslot, they have reached. If the Sox are deadeye accurate in their scouting and evaluation, that strategy will work; if they aren't, it's a huge fail. (And I realize I'm in the minority in questioning this strategy).
Regardless, it's hard to build a contender from ground 0. But I think the Sox are off to a decent start with the pitching. Put some Free Agent money into a couple of sticks.
