The case can be made that Nikki Bella is the most improved wrestler of the past few years. She came in with her sister Brie in 2008, and neither of the Bella Twins were considered to be great workers. For a few years, the Divas division wasnt as important as it is now, and the Bellas twins were for the most part interchangeable and used as arm candy more than they were as wrestlers. The twins left in 2012 but returned a year later in time for WrestleMania, and very quickly WWE sought to add individuality to the personalities of Nikki and Brie. The success of reality show Total Divas highlighted how different the sisters were, and this translated to the wrestling ring as well. Brie became much more technical and aerial based, while Nikkis moves were focused on strength and power. The Rack Attack, or Nikkis Rack Attack is named after its similarity to the submission move the Torture Rack. She gets her opponent up in the reverse Death Valley Driver position, then instead of wrenching on the body like a Torture Rack, she drops down to her knees sharply. Unlike a regular backbreaker, this hits every part of an opponents back putting them out for good and is unusually ruthless compared to what fans have come to expect from a Divas signature move. https://www.youtube.com/watch?v=wfvX3eSMPzs
