#2 Mickie James
Many of you might not know this, but Mickie James was a major part of Impact Wrestling. In fact, before she signed with WWE in 2003, she had wrestled for TNA.
Mickie James was a major force in the TNA Knockouts division and could be more useful in Impact Wrestling as compared to WWE. Feuds with the likes of Tessa Blanchard and Su Yung will not only help the upcoming Knockouts but will also help James remain relevant.
