Does WWE have something "Special" with Kaval/Danielson?

[XL]

I was considering this whilst watching Kaval's debut on SmackDown! this week.

With Kaval you have a small guy with a huge net following. Now, we know that the IWC amounts to a very small % of the total audience so that following counts for pretty much nothing.

However, he is innovative and his offense can be brutal. Watching his match with Drew it seemed that some of the audience was buying into him (given that they probably have no idea who he is) and his offense.

I made a connection between Kaval and Mysterio in terms of how Rey was/is seen as innovative and I wondered how much his inring work counted for how over he is (or is it just the mask?). Can Kaval get himself over with his ringwork alone? Or does WWE need to back him with a gimmick/storyline?

The same question could be asked about Daniel Bryan/Danielson. Another small guy, with an internet following and "different" offense. WWE seem pretty big on him since his return following his return.

Do you think WWE has anything special with these two?
If so, does WWE appreciate what they have with these "Internet Darlings"?
Will they capitalise on it?
