A more recent example, AJ Lee got crazy over through working with Daniel Bryan, CM Punk and Kane.
I absolutely agree - Daniel Bryan was able to get over despite constantly being trashed on commentary because enough people knew his history in RoH, they could see he was being held back. Sadly we can't say the same for Becky's indie work from nine+ years ago, Bayley and Sasha don't have much of a reputation from their time on the indies, and Charlotte has no experience prior to WWE.
Other than vaguely referencing their NXT titles/catchphrases (The Boss, Life Enthusiast, Genetically Superior) and sadly focusing way too much on trying to make Charlotte into L'il Naitch v8.0, we just don't have anything to go on.
