And trades usually hurt, because to get something, you have to give up something. As for bringing up guys from the farm, before the draft in the mid-60s, the rich got richer making high bids for the best prospects. Baltimore was a mid-market exception, because they had maybe better scouts with an organizational plan. Other franchises like San Fran and Pittsburgh were smart enough (and "tolerant" enough) to mine the as-yet untapped Caribbeans and southern Americas.
The modern Red Sox circa the Epstein era did well expanding their scouting efforts on a more global scale. Unfortunately, another underrated factor in the recent fallow farm is the violations that cost us some international prospects; they don't all have to be legit future stars for the talent levels to fill out minor league rosters and up the games and development of prospects.
