I think a reading of the book "Francona, The Red Sox Years" by Frnacona and Shaughnessy is a good way to pass the time before spring training commences. Clearly there is so much that goes on from players health, feelings and interactions that get involved with performance. Also the demands put on teams by the front office needs often are opposed to the best interests of winning. So many personalities and non-baseball related issues are playing out continuously. While Theo was a proponent of data driven decision making, he also understood the needs of Francona to have freedom in keeping the clubhouse together in his own way. All of you hung up on Sabermetrics should read this just to raise your awareness of the real world of team dynamics. Concepts like clutch performance and home field advantage can and are impacted by how a manager can set up a rotation and use players in positions where they thrive.
