The Phillies have a long, outstanding tradition of refusing to let things go. Analytics, desegregation, Domonic Brown's development - you name the movement, and the Phillies have stood in the way of it.
That philosophy translates into their personnel these days. A factoid of contemporary Phillies trivia popped into someone's head a year or so go, and it became common knowledge that the Phillies were at the time still employing not only their last two managers (Larry Bowa and Charlie Manuel), but their last two general managers as well (Ed Wade and Pat Gillick) in various organizational roles.
