His team’s poor record wasn’t entirely Bobby’s fault. In fact, Red Sox general manager Ben Cherington said, “Bobby was dealt a difficult hand.” No doubt Valentine inherited a lot of problems.

But looking ahead, there was no reason for Sox fans to hope that next season Valentine would lead his team differently or deliver a better record.

Obama inherited a lot of problems, too. In his defense, our expectations for hope and change were too high. Unless he Midas-touched his way through the White House, Obama was destined to disappoint us.

But manager Obama has not achieved the goals he led us to believe he would. He has not turned his team around.

You don’t keep a failing manager when there is an acceptable alternative. It’s time for a replacement.
