Some scorn is deserved -- not so much for acquiring the actual players -- but where they're often awkwardly shoehorned into unnatural positions... to the detriment of the team's W-L record.
Franchy isn't a first baseman, Arroyo's not a rightfielder, Marwin wasn't a leftfielder, Duran wasn't a centerfielder last year, and Kike's not a shortstop this year.
Contriving versatility isn't a new concept, but past moves that backfired are notorious in Red Sox lore, like Hanley or Swihart in leftfield. Schwarber was tolerable at first base because he was such a threat with the bat... but Dalbec, we're still not sure can stick in the bigs.
Bloom and Cora both seem complicit, though the latter may have no choice but to only use the parts provided by the former. If the manager indeed has input and influence on building the monster, then it clouds who is Dr. Frankenstein, and who is Igor.
