I understand the PR game and the whole CYA thing.
I don't understand the need for the implication that Hanley would become a problem if his at bats were limited. Why the need to paint Hanley in a bad light? Now maybe he would have become difficult to manage, but maybe he wouldn't have. There is no indication that Hanley has been any kind of a problem since he returned to Boston. Either way, Cora should have just said that he didn't think he would be able to find the playing time for Hanley, and stopped right there.
