Should be called up: Shayna Baszler
While all eyes may be on Ronda Rousey as the face of MMA fighters turned to pro wrestlers, The Queen of Hearts Shayna Baszler has been the quiet workhorse of the Four Horsewomen, the elite cadre of former MMA fighters turned wrestlers that also includes Jessamyn Duke and recent mother Maria Shafir.
While Duke and Shafir were mostly brought in to build up a Horsewomen vs. Horsewomen feud, The Queen of hearts Shayna Baszler was always intended to be a full-time wrestler. She's more experienced than the other members of the Four Horsewomen, including the face of the stable Rowdy Ronda Rousey.
The Queen of Hearts had an impressive run with the NXT women's title, defending it over twenty times this summer alone. Her MMA background, tough as nails demeanor, and legit status as a serious fighter all combine to make her a great superstar.
Baszler is in her mid-thirties, and if pushed to the main roster she could have many good years as a star attraction for Raw or Smackdown.
