#3. Seth Rollins attacking Roman Reigns
Seth Rollins has quietly been the #2 heel on SmackDown, well behind Roman Reigns. Their paths haven't crossed much since, minus a brief confrontation where Cesaro was the central figure.
There might come a time when WWE wants to establish Seth Rollins as SmackDown's top heel in favor of Roman Reigns becoming a babyface, and this might be the catalyst for it all.

It would require careful planning, but ultimately, it isn't the best option to go with if WWE wants to turn Roman Reigns' babyface. It's something that has already been done before in 2014, and recycling it for the biggest face turn of the decade won't be a good idea.
It's better if Seth Rollins has an organic rise to the top as a heel again, while Roman Reigns has an organic babyface turn. They don't need to cross paths in the process, but it would be a bonus if done right. Hopefully, WWE doesn't recycle the Shield breakup storyline.
