#2 Puts odds against Asuka
WWE has a history of stacking the odds against a babyface champion in any way possible and the company is looking to do that again with Sasha Banks versus Asuka for the Raw Women's title. With Bayley in her best friend's corner, there is a very real possibility that Asuka may not come out of Extreme Rules as champion.
And that's what will draw people into this feud: the fact that Asuka may or may not walk out as champion. Now, Asuka is only in the beginning stages of her title reign and most likely won't lose the strap to Banks at Extreme Rules, but it's that slight possibility of Asuka not retaining the strap that will captivate the WWE Universe.
In all honesty, Extreme Rules is one of those B-level pay per views that WWE has to fill out without going full speed ahead and this is a great way to do this. It might even help to make the eventual feud between Banks and Bayley all the more special and really make it a marquee match for SummerSlam.
