Ronda Rousey vs. Stephanie McMahon

This is not exactly a match that could main event one of the 'big four' shows. But Stephanie McMahon vs. Ronda Rousey would've been apt to headline any of the second level pay-per-views. The possibility stemmed from Rousey's appearance at WrestleMania back in 2015 and we all wanted her to step into the ring in 2016 and face Stephanie.

But the loss against Holly Holm proved to be too much for Rousey to handle and she had a complete media blackout after.

This also dashed WWE's hopes of having such a cross over match but we cannot completely rule out the possibility of this happening in 2017.
