#2. Roman Reigns vs. Daniel Bryan could lead to rematches
Roman Reigns vs. Daniel Bryan has a lot of benefits to it and while one of them is the dream match status that it could take on, one has to remember the bigger picture. Beyond that, one also has to remember that WWE is supposedly looking to pad out Roman Reigns' storylines until WrestleMania season.

If this is WWE's intended purpose and if the company really struggles to find babyfaces to battle Reigns, it would make sense for them to go with some kind of rematch scenario. That way, the company has more time to build another opponent, WWE pads out the needed time and Reigns grows as a heel.
For example, what if WWE does Bryan vs. Reigns and brings in Jey Uso to run interference? Not only would that automatically open things up to a rematch between the two due to the cheating, but it would also be a chance to add another layer to the rivalry.
