I think the big knock was the sheer number of prospects he traded away. I once counted about 20 prospects traded that were, at one time or another.
IMO, the hindsight view shows he did well keeping Devers, Bello, Casas, Duran and others, whether he got luck or otherwise, and many of the more highly rated prospects traded, mostly underperformed expectation.
The Sale trade was great: the extension was not.
The Kimbrell trade looked like a gross overpay to me, but the cost of top closers skyrocketed shortly after the trade, and the players we gave up did not do all that well.
The Pom trade looked s***** to me, but Espinoza never did squat.
The Thornburg and C Smith deals sucked, but what we gave up wasn't a killer.
If Bloom makes just one- not 4-5 trades- and brings us the next Sale, I'd be happy, even if we lost a couple top prospects.
