Mark Rosen of the University of Michigan dissects the previous season of competition in order to plan for the upcoming season. Every year Rosen reasseses: What players did we lose? What was unsuccessful? Who are we gaining? What was successful? Statistics can be a good starting point for season evaluation. For Rosen, the primary statistic he scrutinized was kill percentage—if his team couldn’t put a kill away, solid defense and tough serving could not pick up the slack.For Michigan, Rosen isolated several more factors that lead to their record: a low kill percentage and a low blocking percentage. Rosen also reflects on the strengths of each season that he knows the team can rely on going into the new season. Taking both a detailed and bigger picture look at the previous season can guide a program to the next level.
