Either for not getting the lefty starter the Yankees need or for not having the prospects to do so.
Cashman has been inert two years in a row as the Red Sox get the two lefty starters the Yankees desperately needed.
2015: David Price
2016: Chris Sale.
Hal Steinbrenner is inept for not holding Cashman to account. The Yankees are bad and boring, a deadly combination, because the decision makers are dumb and lazy, also a deadly combination.
