7. Bayley Debut
Bayley is on a big push down in NXT, and is scheduled to wrestle Sasha Banks for the Women's Title this Saturday at NXT Takeover Brooklyn. What could happen, is she then turns up at SummerSlam for her full WWE debut. Maybe Sasha wins in controversial circumstances on Saturday, so Bayley turns up on Sunday to exact revenge. It would give a lift to what has been a dire 'Divas Revolution' on the main roster. The Team Bella versus Team Bad versus Team PCB narrative has been woeful. Throwing Bayley into the mix could at least help create a memorable moment on Sunday, and she's more than ready for a main show spot.
