Giants: How the Gabe Kapler hire impacts five key people

San Francisco Giants catcher Buster Posey
Bruce Bochy was the only manager that Buster Posey has ever known, so it was going to be an adjustment no matter who replaced him.
With Kapler in charge, Posey and the rest of the clubhouse fully understands that the old guard is gone and the new one has taken over.
It’s reasonable to assume that Posey might not feel the same sense of security that he once did as one of the few players left who was a part of the championship years. Change is coming, and even a player of his caliber is not immune to that change.
He knows that if he does not turn things around, those great memories may not mean a whole lot to the suits who are shoveling numbers into their analytics machine if they decide that he’s not worth having around anymore.
Hopefully, the Kapler hire will motivate Posey to prove that he’s still capable of being an impact player since he’ll no longer be playing in front of a manager who saw him every day at his peak.
