You’re so wrong it’s not even funny. She did this because she WANTED to. Did her two losses accelerate her joining WWE? Yes, but she’s admitted to being a huge fan before joining WWE, before her losses, so much to the point where her idol, Roddy Piper, passed the nickname “Rowdy” down to her before he passed away.
This was going to happen regardless because she is, and always was a huge fan.
And while her attitude may have been **** in UFC, reports were that she’s amazing to work with in WWE and has no ego and is super coachable.
