Among the time-honored customs inside the White House is for the outgoing president to leave a handwritten note for the incoming president. Placed atop the Resolute desk in the Oval Office, the note is meant to be hopeful and forward-looking, with perhaps a dose of advice from someone who understands the pressures of the job. I’m beginning to wonder if outgoing Red Sox manager John Farrell left a similar message for the man who replaced him, Alex Cora. Case in point: Red Sox shortstop Xander Bogaerts continues to make reckless, common sense-defying headfirst slides into first base.
