If not Bayley this is really the only other acceptable choice. I can picture the crowd reaction in my head.
Not Bayley???
Oh **** it's Asuka...
OH **** IT'S ASUKA!!!
*commences Asuka's gonna kill you chant*
Anyways watch the WWE bookers totally screw this up by doing something stupid like sending Eva Marie despite being drafted to Smackdown so they can brand Sasha and Eva something dumb like Team Hair Die.
Personally I don't think they will be that stupid, but as much as I want it to be Asuka or Bayley they're likely going to do something boring and utterly mundane like throw poor Paige out there. None of those girls in the ring will deserve the crowd reaction something like that would bring.
