#1 Kaitlyn

She is the definition of a performer, and make no mistake if I say that on this list she must be the one who challenges Becky Lynch before anyone else.
She got into great feuds during her initial run, and now that she decided to return, it makes sense she gets the opportunity to challenge 'The Lass Kicker' for the championship.
Is this man the funniest man in wrestling?
She could return as a mystery opponent after Becky Lynch gets on Paige's nerves, stating that she is the best in the WWE, and also 'The Man'. Paige could ask her to be in the ring for her mystery opponent, and Kaitlyn would show up.
The pop she received during Mae Young Classic would compare nowhere to the one she would get during this entrance. This would be the best way to kick-start Becky Lynch versus Kaitlyn in days to come, and would be 'best for business.'
