#3 To push Dolph Ziggler out of WWE programming
Dolph Ziggler's WWE career has essentially whithered away - atleast from a creative standpoint. Given how much WWE would get behind him and then lose interest, we don't blame him for not being particularly motivated.
Moreover, Ziggler is establishing multiple different careers outside of wrestling right now and WWE is giving him the freedom to do so. Again, we don't blame him for having an exit strategy. With that said, he keeps re-signing and lately, he hasn't appeared much until the end of May.
This match may have been a way to push Dolph Ziggler out of WWE programming again. Now that he finished his feuds with Kofi Kingston and Kevin Owens, there isn't too much left to do.
There was a rumoured Ziggler feud with Ali, but we don't really see that doing much for Ali in the long run.
