Every season brings the potential for individual and group failure. In 2015, the Red Sox certainly gave us more group failure than anyone could have anticipated. Coming off the disater of 2014 it was back-to-back misery.
Players come in and sometimes they are new to the team and simply fail. Others come in and do the opposite. A cosmic dance for baseball with a very thin line that impacts performance. An injury, marital problems, sheer laziness or just some quirky anomaly that ruins a season and, hopefully, does not set in motion a career trend.
For the negative there is always the positive that surfaces.
