#3. Roman Reigns vs. Daniel Bryan only viable option
While Roman Reigns vs. Daniel Bryan would be nothing short of a dream match for Friday Night SmackDown, it is also the only option WWE really has at the moment. Now, that doesn't mean that other SmackDown Superstars can't be prepped for the role later, but Daniel Bryan is the only viable option for this situation.

Not only is that evident by SmackDown's lack of babyface characters, but also by how little momentum their remaining good guys have. In all honesty, no one really has the right to step up to Roman Reigns right now, which is why WWE needs to be very careful about who they pick.
In the end, WWE could go with Kevin Owens, Big E, or any of the other babyfaces working their way up the mid-card, but nothing would be more productive than Bryan vs. Reigns. Furthermore, nothing else would really deserve the dream match moniker that Bryan vs. Reigns has.
