It's kind of a Rock and Hard place situation.Rock / Roman doesn’t need a title since the conclusion is already written in stone.
losing the titles to the rock would be the most shortsighted decision in wrestling history. All that positioning and build just to transfer all that heat to… a nikka that shows up once every 3 years
No way
You want any guy that beats Roman to be on a big stage and win cleanly.
The next best thing I would do is... At Royal Rumble. The Uso are barred from ring side. So, Roman phones the Rock in his corner. Rock does a gullibe act and Roman tries to be a face around him.
When it comes to the title match... Roman is gonna ask the Rock to help him out and Rock just says "No" and walks off. Roman loses clean.
