It was reported last month that the other reason Mickie James was moved to SmackDown — besides an apparent weight issue — was because she was getting heat for being too emotional about a relationship she was previously involved in. Hence, certain people on Raw wanted her moved to SmackDown and "out of their hair."
For those curious, the person in question is John Cena, as she had not quite gotten over their split the previous year. Cena has since gotten married with James still having feelings for him, which led to friction backstage.
