#2 Lita

When you think of the two greatest women's wrestlers in WWE before 2014 onwards, two names stand out - Lita and Trish Stratus. This isn't to say there wasn't any other talent, but even when accounting for stars like Mickie James and Beth Phoenix, it's hard for them to touch the legacy that Lita and Trish Stratus left behind.
Lita inspired a whole generation of female wrestlers and if it wasn't for her, there would be no AJ Lee and many other names that we see today. She stood out because of her "daredevil"-like personality and the fact that she could hang with some of the best male wrestlers as well.
In the Women's division, she created a legacy that would take a decade for other women to touch. Her career ended in 2006 at the age of 31, citing various issues and some nagging injuries. While she would make occasional appearances in WWE and the independent scene, that was the end of her career. Had WWE been going in a better direction, we don't doubt that she would have stayed another four years atleast.
