Literally writing the book on the Ray's system of doing things does not mean Bloom will end up being a success as the Sox GM, but my guess is he knows the ins and outs of a winning system. I don't think it's going out on a limb to think knowledge is usually a good thing.
Click and Friedman have been unqualified successes with their new teams, but they have had time and mostly less restricted budgets over their time as GMs.
It takes time to build a farm and then more time before the success is realized. I'm not saying Bloom has succeeded in building up the farm to some great level, because we won't know for a few more years, but on paper, he seems to have done a fine job in that area.
So far, he has done very well with under-the-radar additions, like Whitlock, Schreiber, Refsnyder, Arroyo, Wacha and others.
The area Bloom has seemed to be lacking is with some of his trades and FA signings. It's easy to explain away the results based on having very limited winter spending budgets and too many slots to fill, but the Story signing, in March, broke open the bank. To me, the judgment day began when he signed Story and the rest of his legacy will largely depend on what moves he makes, this winter. He has some big shoes to fill, but he laos has enough dead money coming off the books to create an expectation of him having enough to build a better team than we have had the last 2-4 years.
He may very well prove to be "over his head" or "clueless" or whatever people want to call it. Those terms all seems pretty similar, to me. I'm optimistic he will be up to the task. I don't see the Story signing as completed, yet, and I'm encouraged by the signings like Wacha, Strahm and last year's Kike & Renfroe, but he has to have more signings like those and less like Richards and Diekman.
We'll see if he's done with making the farm the highest priority, and most of his trades have involved adding prospects, so it's hard to judge them on face value, since the value is largely speculative and potential. We can say with near certainty the JBJ trade was a bust, but was that outweighed by the Pivetta deal? If German amounts to anything, we may view the Ottavino deal as brilliant. If Wink or some far away prospect makes good, maybe we view the B eni trade much differently. Maybe a prospects acquired at this deadline ends up shining. It may end up being under the next GM, but the fact is, the jury is still out and maybe way out on final judgments on most of his trades.
Maybe, we'll look back and shake our heads in disgust, but I'm still optimistic we are on the right path.
