Well, you might have a point. After all, Sale did cut up those jerseys, which, despite how anyone wants to rationalize it, was an extremely selfish and childish thing to do.
That said, the way that the pitchers were all approaching Cora in the offseason, letting him know that they were available to pitch in whatever capacity Cora needed, leads me to believe that there was not much, if any, selfishness going on with this team.
