The feud between AJ and Kaitlyn is bound to end, most probably even before Summer Slam, their last match taking place at MITB*. But as soon as Kaitlyn is out, what Diva could challenge AJ for her title?
Here are some opinions on the different Diva's possible, N being me, S being Stefan.
Layla
N: She is probably the most obvious pick, creeping around the ring and Kaitlyn almost all of the time. As being a champion before she should that she at least could hold it in the past.
S: Being one of the last remaining face Diva's that could at least look a bit serious in ring, Layla seems to be the only possible challenger.
Natalya
N: Since she had been aligned with Khali, Natalya lost a lot seriousness. She has been misused my the WWE for the last year and would stand no chance against AJ, not even able to provide a good match.
S: She is only used to promote Kaitlyn's strength. As long as she is the arm accessory of Khali, she is no championship material.
Alicia Fox
N: Who? No seriously, when did we last see her wrestle outside of NXT? No. She might be a former Diva's champion, but these times are long gone!
S: Is she face? Is she heel? The WWE uses her as a filler and nothing more. She even loses at NXT. When had been the last time she had been seen on a main show?
Tamina
N: Probably, speaking of strength, the strongest diva in the current roster, but also one that is seen only on rare occasions. No chance...
S: Being promoted as a heel she shouldn't be able to go against another heel. And, as far as I know, she is currently injured anyway.
Naomi & Cameron
N: Hahahaha, no.
S: In my eyes, they are clearly no wrestlers, but merely dancers for Tons of Funk.
The Bellas
N: That could be a possibility, either Nikki or Brie getting a title shot, but where are they? Too busy with Total Divas?
S: No chance for a title, because they are both occupied with Total Divas. They haven't been seen in the main shows for quite some time now. And who should get the title without them arguing over it in the end? Besides, they are heels as well.
Other
N: A possibility that I strongly see is that there will be a diva none of us had thought about so far. Namely the call of Paige to the main roster, giving her a feud against AJ right away.
