Using Daniel Bryan's MMA and grappling skills as a draw for SummerSlam

I appreciate what WWE is trying to do with Daniel Bryan as we lead up to SummerSlam. They build him up as an underdog who is persistent. That is fine.

Now it is time to put over how dangerous he is. His grappling skills are well known and celebrated.

The Xtreme Couture MMA gym has put over how good he is. So why is this not being promoted on tv? This would do a lot for Bryan's credibility, and build him up as a real threat to John Cena. This surely would lead to more people watching SummerSlam, in the interests of seeing whether Bryan can unseat Cena?
